PIC10F200/202/204/206 TABLE 3-2: PIC10F200/202/204/206 PINOUT DESCRIPTION Name GP0/ICSPDAT/CIN+ GP1/ICSPCLK/CIN-GP2/T0CKI/COUT/ FOSC4 GP3/MCLR/VPP Function Input Type Output Type GP0 TTL CMOS Bidirectional I/O pin. Can be software programmed for internal weak pull-up and wake-up from Sleep on pin change. ICSPDAT ST CMOS In-Circuit Serial Programming™ data pin. — Description CIN+ AN GP1 TTL CMOS Bidirectional I/O pin. Can be software programmed for internal weak pull-up and wake-up from Sleep on pin change. ICSPCLK ST CMOS In-Circuit Serial Programming clock pin. — Comparator input (PIC10F204/206 only). CIN-AN GP2 TTL Comparator input (PIC10F204/206 only). T0CKI ST COUT — CMOS Comparator output (PIC10F204/206 only). FOSC4 — CMOS Oscillator/4 output. GP3 TTL — Input pin. Can be software programmed for internal weak pull-up and wake-up from Sleep on pin change. MCLR ST — Master Clear (Reset). When configured as MCLR, this pin is an active-low Reset to the device. Voltage on GP3/MCLR/VPP must not exceed VDD during normal device operation or the device will enter Programming mode. Weak pull-up always on if configured as MCLR. CMOS Bidirectional I/O pin. — Clock input to TMR0. VPP HV — Programming voltage input. VDD VDD P — Positive supply for logic and I/O pins. VSS VSS P — Ground reference for logic and I/O pins. Legend: I = Input, O = Output, I/O = Input/Output, P = Power, — = Not used, TTL = TTL input, ST = Schmitt Trigger input, AN = Analog input 2004-2014 Microchip Technology Inc. DS40001239F-page 9
