Nuremberg, Germany, February 14, 2001 - At the Embedded Systems show, STMicroelectronics today presented a new 16-bit automotive-grade microcontroller chip with 256K of embedded Flash memory based on the 16-bit ST10 core. Targeting applications such as engine control, the new chip is the fastest ST10-based microcontroller with embedded Flash memory and operates at speeds up to 40MHz. This makes the ST10F269 possibly the fastest 16-bit embedded flash microcontroller. The ST10F269's Flash memory is based on ST's successful standalone single-voltage Flash memory technology and operates at 5V. Reprogramming of Flash content is entirely controlled by a dedicated erase and program controller that allows Flash content to be changed through simple commands. This controller also allows new operating modes such as a read/program operation of a second block during the erase suspend of a different block. Each of the seven embedded Flash memory blocks can be separately protected against programming and erasing to enhance system safety. A memory read protection feature prevents attempts to read out firmware from the chip. Building on its long experience in standalone and embedded flash memory, ST guarantees data retention times of 20 years and at least 100,000 programming cycles for the ST10F269. This performance is guaranteed over the entire -40°C to +125°C automotive temperature range, underlining the Company's leadership in Flash memory technology. Features of the ST10F269 include: 16-bit 40MHz ST10 Core Integrated 40-bit wide Multiply-Accumulate unit PLL 256Kbytes Flash with 100K program/erase cycles 12Kbytes RAM Zero-overhead loops on MAC operations Real-time clock Two Watchdog timers - one for software & one for clock Two 16-bit multi-function timers Two capture/compare units with 16-bit timers 4-channel PWM unit 16-channel 10-bit A/D converter with 4.85µs conversion time Two UARTS SPI Two CAN modules Up to 111 I/O pins 5V operation (internal regulator supplies 3.3V to core) Automotive temperature range -40 to +125°C 0.35µ embedded Flash technology with 20 years data retention PQFP-144 package Available now for OEM customers Commercially available end of 2001 for $20 in 10Ku quantities Fast wake-up from interrupt-driven power-down supports power saving schemes; and current consumption in power-down mode when system clocks are stopped is 500µA. Driven by the demand to execute signal processing algorithms more efficiently, the ST10F269 integrates a 40-bit wide Multiply-Accumulate (MAC) unit. The ST10F269 applies an optimized instruction set extension that exploits the advantages of the MAC unit by performing nearly all instructions in 50ns at the maximum clock speed. A smart repeat unit suppresses software overhead on DSP algorithms, reducing code size for these routines. Development Tools Tasking provides support for the ST10F269 with its C++/C/ECC compiler toolchain and Keil with its C compiler and cycle-accurate debugger. Lauterbach, Hitex and Nohau provide emulation support for the ST10F269. Evaluation boards are available from FS-Forth Systems.
