3 / 27 page  SPMC802B 32-PIN GENERAL PURPOSE MICROCONTROLLER (OTP) 1. GENERAL DESCRIPTION The SPMC802B is an OTP version of SPMC02A with reliability enhancement. It equips with an 8-bit Sunplus CPU core, 4.5K bytes of program ROM, and 128 bytes of RAM. SPMC802B also combines with four I/O ports, two timers with one PWM output, two Comparator inputs, and a Watchdog Timer. Three groups of interrupt are implemented for different kinds of applications. Major application fields are small home appliances or computer peripheral applications. The details are described below. 2. FEATURES ! Built-in 8-bit Sunplus CPU core with two index registers and up to 6MHz clock operation. ! 28 general-purpose I/O channels that are belong to four I/O ports. Some of them are combined with the options to select Pull-Up/Down Resistors. ! Three external interrupt groups, one is come from individual I/O Channel PB5 and group input PA3:0, one is come from individual I/O Channel, PA7, and one is a group input, PC port. ! External Reset input option on PB4. ! An 8-bit Timer with Real Time Interrupt control. ! An 8-bit Re-loadable Timer with 8 stages prescalar. ! One 6-bit PWM waveform output. ! Two voltage Comparator inputs with selectable internal or external voltage reference. An interrupt event control for the compare result. ! A watchdog timer for program control. ! 4.5K bytes of ROM with 128 bytes of RAM. ! R-Oscillation or Crystal input options for system clock. ! Stop or Wait Control setting for Power-Saving Mode. ! Slow Transition Output Pins. 3. BLOCK DIAGRAM OSC.
