GENERAL DESCRIPTIONTM52 series F0C63 are versions of a new, fast 8051 architecture for an 8-bit microcontroller
single chip with an instruction set fully compatible with industry standard 8051,
and retains most 8051 peripheral’s functional block. Typically, the TM52 executes
instructions six times faster than the standard 8051 architecture.
The TM52-F0C63 provides improved performance, lower cost and fast time-to-market by
integrating features on the chip, including 8K Bytes Flash program memory,
128 Bytes EEPROM, 512 Bytes SRAM, Low Voltage Reset (LVR), Low Voltage Detector (LVD),
dual clock power saving operation mode, 8051 standard UART and Timer0/1/2,
real time clock Timer3, 7 set 16-bit PWMs, 19 channels 12-bit A/D Convertor,
master I2C interface and Watch Dog Timer. It’s a high reliability and low power consumption
feature can be widely applied in consumer and home appliance products.
