WT5109
【 General Description 】 |
The WT5109 is an 8-bit RISC architecture microcontroller with high performance designed for A/D product applications that connect to analog signals directly. The additional PWM modulation function enhances the analog capability of this device. The program memory is an In-System programmable OTP (one time program) ROM. This chip integrated multi-channel A/D converter and PWM functions, high performance timer functions, oscillator options, I/O flexibility and low cost. The WT5109 provides wide applications for products at home and in industrial areas. |
