This month's issue:
Atmel announced the availability of the ATA6602 and ATA6603
multichip modules, extending their IC family for LIN applications. These new
devices are designed for automotive actuator applications typically found in
comfort electronics (e.g., window lifter, mirror or seat adjuster) as well as in
powertrain applications. Due to their very small size, the ATA6602 and ATA6603
are also ideal for sensor node applications such as control panels, air quality,
rain/sun sensors and many more.
Using a multichip-module approach, these two ICs combine a microcontroller
(8-bit AVR) and a LIN system basis chip (LIN SBC) in a single package (SiP,
system-in-package). The ATA6602 integrates
the automotive-qualified ATmega88 AVR Flash MCU with 8 kB of Flash memory,
whereas the ATA6603 incorporates the automotive-qualified ATmega168 with a Flash
memory of 16 kB.
The LIN SBCs within the new ATA6602 and ATA6603 modules incorporate the LIN
transceiver, an advanced voltage regulator, and a watchdog timer. They are
manufactured using Atmel's own high-voltage BCDMOS process for operation in
harsh environments. Thanks to its silent mode, the LIN SBC provides very low
power consumption (40 microamps with activated voltage regulator). In addition,
the LIN SBC provides high immunity against ESD and EMC, various protection
functions, and a unique, broad input/output voltage range (-40 to 60V) for the
LIN bus pin which is ideal for use in truck applications.
Since the ATA6602 and ATA6603 incorporate AVR microcontrollers with all pins
bonded out, Atmel's standard AVR tools can be used during the development phase.
This includes the AVR Studio IDE for writing and debugging AVR applications. AVR
Studio includes an assembler, as well as a simulator, and supports the
integration of the freeware GCC compiler. For on-chip debugging, the AVR JTAGICE
mkII with debugWIRE interface can be used. A LIN protocol handler is also
available. In addition, a LIN software library for GCC and IAR C compiler are
available for free.
Samples of the new ATA6602/ATA6603 in QFN48 (7 x 7 mm) packages are available
now. Pricing for 10,000 units starts at $1.87 (ATA6602) and $1.99 (ATA6603).
Freescale Semiconductor is extending its low-end 8-bit 908Q
microcontroller family with the introduction of the high-performance MC908QC16
Offering 16kB of Flash memory, the highly integrated QC16 MCU
eliminates the need for external components such as low-voltage
inhibit (LVI), oscillators and drivers with high-current I/O. The
high-performance Flash memory read/program/erase functionality supports EEPROM
emulation, eliminating the need for external EEPROM.
Features include 24 GPIO, 2.2V to 5.5V operation, -40 to +125 degrees C range,
ESCI, SPI, high-speed asynchronous operation at full duplex, 10-bit ADC with
internal reference voltage, internal clock oscillator with 3.2 MHz nominal
frequency (or 2 MHz at 2.2V), and 4-channel 16-bit timers.
The QC16 MCU is housed in a 16-pin TSSOP. The suggested resale price is $1.94 in
Introduces First S08 MCU with LCD Driver
Freescale Semiconductor has introduced a family of highly integrated,
power-efficient 8-bit MCU devices optimized for LCDs. The MC9S08LC60 (LC60)
family features Freescale's first S08-based Flash MCUs to include an integrated
LCD driver module with an internal charge pump.
The LC60 family's integrated up to 160 (4x40) segment LCD driver supports both standard 3V and 5V LCD
glass applications. An internal charge pump enables the application to run off
of a single power supply, a dual supply for sustained contrast, or a customized
implementation of contrast control.
The LCD driver can be configured to operate a display even when the MCU core
enters STOP or "sleep" mode. The blinking of individual segments in STOP mode is
an innovative feature that helps reduce overall system power consumption and
preserves battery life.
The LC60 family features a dual Flash memory block for enhanced EEPROM
emulation. Eliminating extraneous EEPROM from the system helps reduce system
cost and board space. The dual Flash block enables continued execution of code
out of one block while programming or erasing the other block.
On-chip integrated SPI, SCI and I2C modules make it easy to connect LC60 MCUs to
external power measurement ICs or to ZigBee-enabled modules for wireless
The LC60 family features the MCS08LC60 and the MCS08LC36. Volume quantities of
both devices in an 80-pin LQFP are available now, and volume quantities for
64-pin LQFP devices are planned for Q2 2007. The suggested resale price for the
MCS08LC60 in 10,000-piece quantities starts at $3.70, and the suggested resale
price for the MCS08LC36 starts at $3.14.

of alpha samples were shipped to multiple customers over the last seven months.
engine technology provides high throughput and strict real-time operation by
handling intensive security algorithms without taxing the DSP cores. Performing
the security algorithms within the MSC8144E enables system scalability and
eliminates the need for expensive external logic to perform these tasks. The security engine supports the DES, 3DES, Kasumi-F8, MD-5,
SHA-1/2, AES 128-256, HMAC and ARC-4 data encryption algorithms, and it offers a
public key exchange (PKE) and random number generator (RNG). A CodeWarrior tool
suite is available to support the security extensions.
In addition to data encryption, the MSC8144EC enables a code-protection
mechanism implemented in hardware with a dedicated encrypted key for OEMs. This
feature helps to prevent OEM software programs from executing on unauthorized
devices, or from being copied or modified by unauthorized entities.
The MSC8144E and MSC8144EC are pin- and package-compatible with the existing
MSC8144, enabling existing customers to upgrade their systems easily. Based on
Freescale's advanced 90nm silicon-on-insulator process technology, the devices
embed four StarCore SC3400 DSP cores each running at up to 1GHz, generating
equivalent performance to a 4GHz single-core DSP. The MSC8144, MSC8144E and

data RAM and 1088kB of Flash memory with read-out protection.
A 100MHz PLL clock circuit minimizes power consumption by dynamically switching
off unused clock trees. Further power-saving features include an integrated
32kHz sub-clock oscillator in conjunction with standby modes such as "stop" and
"sleep". Security and safety applications are supported by the internal clock
supervisory circuit, which automatically switches to an internal RC-oscillator
as backup in the event of a main clock failure.
Flexible timer architectures as well as the capability to generate and capture
high-precision signals are basic requirements for automotive systems. The
MB91F467B provides 8x16-bit free-running timers, an 8x16-bit reload timer and 16

Texas Instruments has announced volume availability of the
MSP430FG461x series of ultra-low-power MCUs with up to 120KB Flash memory. As
the first devices to incorporate the MSP430X architecture with extended 1MB
memory model, the MSP430FG461x series is designed for today's larger system
memory requirements and allows for the development of very sophisticated
real-time applications, completely in modular C libraries with full backward
compatibility. The extended memory model also enables faster code execution that
results in up to 50% reduction in cycles for a full context store and up to 25%
when addressing peripherals, Flash, or RAM.
As the first MSP430X device, the FG461x MCU series includes up to 120KB of Flash
and up to 8KB RAM. Up to three operational amplifiers to handle high-precision
instrumentation -- coupled with the on-board 200ksps 12-bit ADC, 1 micro-second
code-to-code settling time 12-bit DAC, and DMA controller -- complete a
signal-chain-on-chip (SCoC) solution that reduces overall system cost and
eliminates the need for external components. The 3-channel DMA eliminates data
transfer delays to the on-chip DACs, ADC and other peripherals and frees up the
16-bit RISC MSP430X CPU to spend time processing data, instead of performing
"handling" tasks. Also, compared to using an external DAC and software, the
MSP430FG4xx on-chip DAC module, coupled with the DMA, provides a greater than
ten times increase in achievable analog output signal frequency.
From a single coin cell, the FG461x MCU can operate for up
to 10 years by consuming less than two micro-amps in a real-time-clock stand-by
The MSP430FG461x MCU series provides designers with pin-for-pin memory migration
from the MSP430F449 MCU. The FG461x series of MCUs are immediately available in
volume quantities and start at $9.45 per 1,000 units.
