GENERAL DESCRIPTION The SN8P1702A/SN8P1703A is a series of 8-bit micro-controller. This chip is utilized with CMOS technology fabrication and featured with low power consumption and high performance by its unique electronic structure. SN8P1702A/SN8P1703A FEATURES ♦ Memory configuration OTP ROM size: 1K * 16 bits. RAM size: 128 * 8 bits. ♦ I/O pin configuration Input only: P0 Bi-directional: P1, P4, P5 Wakeup: P0, P1 Pull-up resisters: P0, P1, P4, P5 External interrupt: P0 P4 pins shared with ADC inputs. ♦ Two 8-bit timer counters. (TC0, TC1). ♦ On chip watchdog timer. ♦ Eight levels stack buffer. ♦ 59 powerful instructions Four clocks per instruction cycle All of instructions are one word length. Most of instructions are one cycle only. All ROM area lookup table function (MOVC) ♦ Three interrupt sources Two internal interrupts: TC0, TC1 One external interrupts: INT0. ♦ An 4-channel 12-bit ADC ♦ Two channel high speed PWM output. ♦ Two channel Buzzer output. (BZ0/BZ1) ♦ Dual clock system offers four operating modes External high clock: RC type up to 10 MHz External high clock: Crystal type up to 16 MHz Internal low clock: RC type 16KHz(3V), 32KHz(5V) Normal mode: Both high and internal low clock active Slow mode: Internal low clock only Green mode: Periodical wake-up by timer Sleep mode: Both high and internal low clock stop ♦ Package (Chip form support) SN8P1702A -- PDIP 18 / SOP 18 / SSOP20 SN8P1703A-- PDIP 20 / SOP 20 / SSOP20
