It is a one-chip microcomputer that executes industry standard instructions developed in 2005.In addition to 8-bit ADC and DAC, I2C, SPI, EIA-232 are equipped with three types of
serial I/F.
OTP-ROM is equipped with 2 kW. SRAM is equipped with 256 bytes.
It operates at 16 MHz with 1 Instruction / Cycle RISC architecture. Compared to Z80 etc., it is processing capacity equivalent to 64 MHz.
It is also suitable for battery operation, and it consumes approximately 1.5 uA even when it operates a wake-up timer at Sleep.
