MC68HC68R2 - 8-BIT SERIAL STATIC RAMs

Download the MC68HC68R2 datasheet PDF. This datasheet also covers the MC68HC68R1 variant, as both devices belong to the same 8-bit serial static rams family and are provided as variant models within a single manufacturer datasheet.

Description

the SS pin, is required for the RAM serial interface logic to become enabled.

The device is held in the reset state if either CE is low or SS is high.

® MOTOROLA Advance Information 8-BIT SERIAL STATIC RAMs The MC68HC68Rl and MC68HC68R2 are serially organized 128-word (MC68HC68Rl) or 256-word (MC68HC68R2) by 8-bit static random access memories (RAMs). These RAMs are intended for use in systems where minimum package and interconnect size, low power, and simplicity of use are desirable; for example, in systems utilizing synchronous serial 3-wire (clock, data in, data out) interfaces. Interface can I be made with the MC68HC05D2 without additional components, provided the MC68HC05D2 SPI control register bits CPHA and CPOL are set. • Fully Static Operation • Operating Voltage Range: 3 V to 5.
