HT48CA1 - (HT48RA1 / HT48CA1) Remote Type 8-Bit MCU

Download the HT48CA1 datasheet PDF. This datasheet also covers the HT48RA1 variant, as both devices belong to the same (ht48ra1 / ht48ca1) remote type 8-bit mcu family and are provided as variant models within a single manufacturer datasheet.

General Description

The HT48RA1/HT48CA1 are 8-bit high performance, RISC architecture microcontroller devices specifically designed for multiple I/O control product applications.

The data ROM can be used to store remote control codes.

Key Features

  • Operating voltage: 2.0V~5.5V.
  • 23 bidirectional I/O lines (max. ).
  • 1 interrupt input shared with an I/O line.
  • 8-bit programmable timer/event counter with overflow.
  • HALT function and wake-up feature reduce power consumption.
  • 8-level subroutine nesting.
  • Up to 1ms instruction cycle with 4MHz system clock at interrupt and 8-stage prescaler (TMR0).
  • 16-bit programmable timer/event counter and VDD=3V.
  • Bit manipulation instruction.
  • 16-bit table read in.
