The HF88S05 is a command mode SRAM device. It features dual (parallel and serial) command access modes. Multiple device arrays can be accessed with only minimal additional device select pin. Simple Exclusive OR checksum provides error detection during data transfer between MCU and the device. The interface logic and protocol include setting up the starting address for data transfer, writing data into RAM, as well as read it back for verification, and error checking by Exclusive OR checksum. It can be used for Read/Write memory extension for all KB's MCUs.
Chip Select pins allows array of HF88S05 devices are used simultaneously for both parallel and serial transfer mode. In the serial mode, the HF88S05 is connected in daisy chain configuration to minimize the I/O pins required to use multi-chip array, while in parallel mode, the devices share most of the control pins and data bus except the chip select pins.
