Description
SH69K20A is a single-chip micro-controller integrated with SRAM, ROM, Timer and I/O port, with a built-in 2MHz/4MHz/6MHz RC oscillator.
Features
- SH6610C-based single-chip 4-bit micro-controller ROM: 1K X 16 bits RAM: 96 X 4 bits - System register: 32 X 4 bits - Data memory: 64 X 4 bits
Operation voltage: - fOSC = 400kHz - 4MHz, VDD = 2.0V - 5.5V - fOSC = 4MHz - 8MHz, VDD = 4.5V - 5.5V
15 CMOS bi-directional I/O pins and 1 CMOS input pin Built-in pull-high and pull-low resistor for PORTA, B, C, D (excluding PORTD.3 - no pull-high resistor) 4-level subroutine nesting (including interrupts) One 8-bit auto re-load timer/counter, can be switc.
