HT48R06A-1/HT48C06
8-Bit Cost-Effective I/O Type MCU
Block Diagram
Rev. 1.30 1 August 7, 2003
General Description
The HT48R06A-1/HT48C06 are 8-bit high perfor-
mance, RISC architecture microcontroller devices spe-
cifically designed for cost-effective multiple I/O control
product applications. The mask version HT48C06 is
fully pin and functionally compatible with the OTP ver-
sion HT48R06A-1 device. The advantages of low power consumption, I/O flexibil-
ity, timer functions, oscillator options, HALT and
wake-up functions, watchdog timer, buzzer driver, as
well as low cost, enhance the versatility of these devices
to suit a wide range of application possibilities such as
industrial control, consumer products, subsystem con-
trollers, etc.
