® 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.
