1 / 2 page  128 KB Flash HCS12 CPU 16-Key Wake-Up IRQ Ports Vreg 5V to 2.5V Enhanced Capture Timer 16-bit, 8-ch. ATD0 10-bit, 8-ch. 8 KB RAM 2 KB EEPROM ATD1 10-bit, 8-ch. 2 x SCI 2 x SPI I2C PWM 8-bit, 8-ch./16-bit, 4-ch. Up to 91 GPIO 16-bit Microcontrollers MC9S12A128 Overview Freescale Semiconductor’s MC9S12A128 Flash microcontroller (MCU) is the next 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. 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 > Real-time in-circuit emulation and debug without expensive and cumbersome box emulators > Read/write memory and registers while running at full speed Integrated Third-Generation Flash Memory 2 KB Integrated EEPROM > Flexible protection scheme for protection against accidental program or erase > 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 > In-application reprogrammable > Self-timed, fast programming • Fast Flash page erase—20 ms (512 bytes) • Can program 16 bits in 20 µs while in burst mode > 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 > Flexibility to change code in the field > Efficient end-of-line programming > Total program time for 128 KB code is less than five seconds > Reduces production programming cost through ultra-fast programming > 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 10-bit Analog-to-Digital Converter (ADC) > Two, 8-channel ADCs > 7 µs, 10-bit single conversion time, scan mode available > Fast, easy conversion from analog inputs like position sensors, analog meters and photovoltaic cells to digital values for CPU processing > Can effectively have 3.5 µs conversion time by sampling same signal with both ADCs |
