Product Introduction:PIC10F322T-I/OT Product Introduction

The PIC10F322T-I/OT is a 6-pin 8-bit flash microcontroller from Microchip Technology that packs advanced peripherals into the tiny SOT-23-6 package. Despite having only 4 usable I/O pins, the device integrates a 10-bit ADC with 2 channels, 2 independent 8-bit PWM outputs, a Complementary Waveform Generator (CWG) for half-bridge driving, and a Configurable Logic Cell (CLC) that implements combinatorial and sequential logic without CPU intervention. The 512-word Flash and 64-byte SRAM provide enough code and data space for simple control algorithms. Operating from 1.8V to 5.5V with 0.5 µA sleep current, the device is ideal for battery-powered applications that need small size and intelligent control.

Working Principle:PIC10F322T-I/OT Working Principle

The PIC10F322 uses Microchip’s baseline 12-bit instruction word architecture. The 12-bit instructions encode both the opcode and operand address directly, allowing compact code storage in the 512-word Flash. The ALU operates on data stored in 64 bytes of SRAM using file register addressing. The 10-bit ADC converts analog inputs on 2 pin-shared channels using a successive approximation register. The two PWM modules use Timer2 as the time base, generating 8-bit duty cycle waveforms on two independent output pins. The Complementary Waveform Generator (CWG) takes a PWM input and generates two complementary outputs with programmable dead-band insertion and shutdown control, enabling half-bridge driving for motor and LED applications. The Configurable Logic Cell (CLC) is a small programmable logic block with 4 inputs, configurable gates (AND-OR or OR-AND), and optional flip-flop. It can implement logic functions like AND, OR, XOR, D-latch, and JK flip-flop independently of the CPU, responding to input changes in nanoseconds while the CPU remains in sleep mode. The Timer1 gate feature measures pulse widths by accumulating timer counts only while the gate signal is active.
