GENERAL DESCRIPTION The SN8P1600 series is an 8-bit micro-controller utilized CMOS technology and featured with low power consumption and high performance by its unique electronic structure. FEATURES ♦ Memory configuration OTP ROM size: 1K * 16-bit. (SN8P1602/1603) RAM size: 48 * 8-bit. (SN8P1602/1603) OTP ROM size: 4K * 16-bit. (SN8P1604) RAM size: 128 * 8-bit. (SN8P1604) ♦ I/O pin configuration(SN8P1602/1603 14 pins, SN8P1604 22 pins) Input only: P0 Bi-directional: P1, P2, P5 Wakeup: P0, P1 Pull-up resisters: P0, P1, P2, P5 (SN8P1604 only) External interrupt: P0 ♦ One 8-bit timer counters. (TC1 for SN8P1604, TC0 for others) ♦ On chip watchdog timer. ♦ Four levels stack buffer. ♦ 56 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) ♦ Two interrupt sources One internal interrupt: TC0. (SN8P1602/ 1603) One internal interrupt: TC1. (SN8P1604) One external interrupt: INT0. ♦ One channel 8-bits PWM or Buzzer output. (SN8P1604 only) ♦ Dual clock system offers three 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 low clock active Slow mode: Low clock only Sleep mode: Both high and low clock stop ♦ Package (Chip form support) P-DIP18 (SN8P1602/ 1603) SOP18 (SN8P1602/1603) SSOP20 (SN8P1602/1603) SKDIP28 (SN8P1604) SOP28 (SN8P1604)
