HT46CU25
Overview
The HT46RU25/HT46CU25 are 8-bit, high performance, RISC architecture microcontroller devices specifically designed for A/D applications that interface directly to analog signals, such as those from sensors. The mask version HT46CU25 is fully pin and functionally compatible with the OTP version HT46RU25 device.
- Operating voltage:
- Up to 0.5ms instruction cycle with 8MHz system clock fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V
- System clock (fSYS): 400kHz~8MHz, 32.768kHz
- 48 bidirectional I/O lines (max.)
- One interrupt input shared with an I/O line
- One 8-bit and two 16-bit programmable timer/event at VDD=5V
- 16-level subroutine nesting
- 8-channels 12-bit resolution A/D converter
- 4-channels (6+2)/(7+1)-bit PWM output shared with four I/O lines
- Universal Asynchronous Receiver Transmitter counter with prescaler and PFD (programmable frequency divider) function and overflow interrupt
