General Description

These TinyPowerTM A/D Type with LCD 8-bit high performance RISC architecture microcontrollers are specifically, designed for applications that interface directly to analog signals and which require an LCD or LED interface. The devices include an integrated multi-channel Analog to Digital Converter, Pulse Width Modulation outputs and an LCD/LED driver.
