16-bit Microcontrollers MC9S12DG256 Target Applications > Automotive applications > Industrial control 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 Freescale Semiconductor’s HCS12 Family of microcontrollers (MCUs) is the next generation of the highly successful 68HC12 architecture. Using Freescale’s industry-leading 0.25 µs Flash, the MC9S12DG256 is part of a pin-compatible family that scales from 32 KB to 512 KB of Flash memory. The MC9S12DG256 provides an upward migration path from Freescale’s 68HC08, 68HC11 and 68HC12 architectures for applications that need larger memory, more peripherals and higher performance. Also, with the increasing number of CAN-based electronic control units (ECUs), its multiple network modules support this environment by enabling highly efficient communications between different network buses. > Read/write memory and registers while running at full speed Network Modules > Two msCAN modules implementing the CAN 2.0 A/B protocol • Five receive buffers per module with FIFO storage scheme • Three transmit buffers per module with internal prioritization 2 x SCI I2C Vreg 5V to 2.5V 16-Key Wake-Up IRQ Ports 12 KB RAM 4 KB EEPROM ATD0 10-bit, 8-ch.
