MC68HC908GR4CDW

The MC68HC908GR4CDW is designed as a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

MC68HC908GR4CDW has many features. (1)High-performance M68HC08 architecture optimized for C-compilers. (2)Fully upward-compatible object code with M6805, M146805, and M68HC05 families. (3)8-MHz internal bus frequency. (4)FLASH program memory security. (5)On-chip programming firmware for use with host personal computer which does not require high voltage for entry. (6)In-system programming. (7)System protection. (8)Low-power design and fully static with stop and wait modes. (9)Standard low-power modes of operation of wait mode and stop mode. (10)Master reset pin and power-on reset (POR). (11)7680 bytes of on-chip FLASH memory on the MC68HC908GR8 and 4096 bytes of on-chip FLASH memory on the MC68HC908GR4 with in-circuit programming capabilities of FLASH program memory. (12)384 bytes of on-chip random-access memory (RAM). (13)Serial peripheral interface module (SPI). And so on.

Some absolute maximum ratings have been concluded into several points of MC68HC908GR4CDW as follow. (1)Its supply voltage would be from -0.3V to 5.5V. (2)Its input voltage would be from Vss-0.3V to Vdd+0.3V. (3)Its maximum current per pin would be +/-15mA. (4)Its maximum current for pins would be +/-25mA. (5)Its maximum current into Vdd would be 150mA. (5)Its maximum current out of Vss would be 150mA. (6)Its storage temperature range would be from -55°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MC68HC908GR4CDW are concluded as follow. (1)Its output high voltage would be min Vdd-1.5V. (2)Its output low voltage would be max 1.5V. (3) Its input high voltage would be min 0.7Vdd and max Vdd. (4)Its input low voltage would be min Vss and max 0.2Vdd. And so on.
