16-bit Microcontrollers MC9S12A128 Target Applications > Instrumentation > Energy management > Industrial control > Robotics > Safety equipment > Security Features Benefits High-Performance 16-bit HCS12 CPU Core > 25 MHz bus operation at 5V for 40 ns minimum instruction cycle time > Opcode compatible with the 68HC11 and 68HC12 > C-optimized architecture produces extremely compact code On-Chip Debug Interface > Dedicated serial debug interface > On-chip breakpoints Overview > Real-time in-circuit emulation and debug without expensive and cumbersome box emulators > Read/write memory and registers while running at full speed Freescale Semiconductor’s MC9S12A128 Flash microcontroller (MCU) is the next Integrated Third-Generation Flash Memory generation of the highly successful 68HC12 architecture. Using Freescale’s industry-leading 0.25 µs Flash, the A128 is part of a pin-compatible family that scales from 32 KB to 512 KB of Flash memory. The MC9S12A128 provides an upward migration path from Freescale’s 68HC08, 68HC11 and 68HC12 architectures for applications that need larger memory, more peripherals and higher performance. > In-application reprogrammable > Flexibility to change code in the field > Self-timed, fast programming > Efficient end-of-line programming • Fast Flash page erase—20 ms (512 bytes) > Total program time for 128 KB code is less than five seconds • Can program 16 bits in 20 µs while in burst mode > Reduces production programming cost through ultra-fast programming > 5V Flash program/erase/read > Flash granularity—512 byte Flash erase/2 byte Flash program > Two independently programmable Flash arrays > Flexible block protection and security > No external high voltage or charge pump required > Virtual EEPROM implementation, Flash array usable for EE extension > Can erase one array while executing code from another 2 KB Integrated EEPROM HCS12 CPU > Flexible protection scheme for protection against accidental program or erase 128 KB Flash > EEPROM can be programmed in 46 µs > Can erase 4 bytes at a time and program 2 bytes at a time for calibration, security, personality and diagnostic information 10-bit Analog-to-Digital Converter (ADC) 2 x SCI 8 KB RAM 2 KB EEPROM 2 x SPI Up to 91 GPIO Internal Bus I2C ATD0 10-bit, 8-ch.
