HT46R48E Overview
Description
The HT46R48E 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. There are two dice in the HT46R48E package: one is the HT46R48 MCU, the other is a 128ยด8 bits EEPROM used for data memory purpose.
Key Features
- Operating voltage
- HALT function and wake-up feature reduce power fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V
- 19 bidirectional I/O lines (max.)
- 1 interrupt input shared with an I/O line
- 8-bit programmable timer/event counter with overflow consumption
