描述 Description

The Enhanced A/D Type with LCD is a 8-bit high performance, RISC architecture microcontroller specifically designed for applications that interface directly to analog signals and which require an LCD interface. The device includes an integrated multi-channel Analog to Digital Converter, Pulse Width Modulation outputs and an LCD driver. The benefits of integrated A/D, LCD, and PWM functions, in addition to low power consumption, high performance, I/O flexibility, timer functions, oscillator options, power down and wake-up functions, watchdog timer and low voltage reset, combine to provide device with a huge range of functional options while still main taining a high level of cost effectiveness. The fully integrated system oscillator HIRC, which requires no external components and which has three frequency selections, opens up a huge range of new application possibilities for the device, some of which may include industrial control, consumer products, household appliances subsystem controllers, etc.
