MC68HC11G5

The MC68HC11G5 is a kind of high-density complementary metal oxide semiconductor (HCMOS) microcontroller unit. It includes 16 kilobytes of on-board ROM and is a member of the M68HC11 family of advanced capability MCUs. This device has 512 bytes of on-board static RAM and a nonmultiplexed expanded bus for accessing external memory.

The following is about the features: (1)low-power/high-performance M68HC11 CPU core; (2)16 kilobytes of ROM; (3)256 bytes of bootstrap ROM; (4)512 bytes of static RAM; (5)RAM, registers and I/O mappable to any 4k boundary; (6)expanded non-multiplexed data/address buses give access to a total address space of 64 kilobytes; (7)maximum of seven 8-bit, one 6-bit and one 4-bit I/O ports; (8)2 separate 16-bit timers, each with its own E-clock divider circuitry; (9)external clock option on Timer 2; (10)4 output compare (OC), 3 input capture (IC) and 3 selectable OC/IC channels; (11)4 PWM timers, each with its own counter and programmable period and duty cycle; (12)dual event counter featuring phase-shifter, pulse accumulator, periodic timer and 256 clock divider; (13)8-channel, 10-bit A/D converter with 1, 4 and 8-channel scanning modes; (14)COP watchdog timer and clock monitor; (15)serial I/O system incorporating asynchronous NRZ and synchronous SPI; (16)Single Chip, Expanded, Bootstrap and Test modes of operation; (17)84-pin PLCC package (quad surface mount plastic).
