Datasheet Summary
MCU with 2KB ECC SRAM/32KB ECC E-Flash for Touch Key
GENERAL DESCRIPTION
CS8974 is a general-purpose MCU with 32KB code memory (organized as 32Kx16) of embedded-flash memory and 2KB (organized as 2Kx13) SRAM for data manipulations. Both SRAM and e-Flash implement built-in ECC that corrects 1-bit error and detects two-bit errors. CPU can access the e-Flash through program address read and through Flash Controller which can perform software read/write operations of e-Flash for EEPROM emulations.
CPU in CS8974 is 1-T 8051 with enhanced multiplication and division accelerator. There are two clock sources for the system, one is a 16MHz IOSC (manufacturer calibrated +/- 2%) and...
