HT48CXX/HT48RXX
8-Bit Microcontroller Series
www.DataSheet4U.com
Features
• Operating voltage: 2.4V~5.2V
• Bidirectional I/O lines with a selection of 18,
22, 32 and 56 lines
• One interrupt input
• Programmable timer/event counters with
overflow interrupts and a selection of one
8-bit counter, one 8-bit and one 16-bit count-
ers, or two 16-bit counters
• On-chip crystal and RC oscillator
• Watchdog timer
• Program ROM with size selection of
1K×14, 2K×14, 4K×15 and 8K×16 bits
General Description
The HT48C10/48C30/48C50/48C70 are 8-bit
high performance RISC-like microcontrollers,
specifically designed for multiple I/O product
applications. These devices are suitable for use
in products such as remote controllers, fan/light
controllers, washing machine controllers,
scales, toys, and various subsystem controllers.
They all contain a halt feature to reduce power
consumption. The major differences between
• Data RAM with size selection of 64×8, 96×8,
160×8 and 224×8 bits
• Halt function and wake-up feature to reduce
power consumption
• 63 powerful instructions
• Up to 0.5µs instruction cycle with 8MHz
system clock at VDD=5V
• All instructions in 1 or 2 machine cycles
• 14-bit/15-bit/16-bit table read instructions
• 2-level/4-level/8-level subroutine nesting
• Bit manipulation instructions
these microcontrollers are attributed to vari-
ations in sizes of the ROM and RAM, as well as
bit number, counter number, I/O line number,
and different level subroutine nesting. Roughly
speaking, the HT48C10 is a microcontroller
with most economic features and the HT48C70
is one with the most features of the four micro-
controllers.

Note:
For the dice form, the TMR0 and TMR1 pads have to be bonded to VDD or VSS if the TMR0
and/or TMR1 pad are not used.
The (TMR0) INT indicates that the TMR0 pad should be bonded to the INT pin.
The PC5 (TMR1) indicates that the TMR1 pad should be bonded to the PC5 pin.
