PIC10F322-I/MC Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and peripherals such as timers, ADC, and communication interfaces onto one silicon die. Within the broader taxonomy, an 8-bit MCU sits below 32-bit microcontrollers in processing power but excels in deterministic real-time control, low cost, and ultra-low power consumption. The PIC10F family represents Microchip's smallest-footprint 8-bit line, aimed at replacing discrete logic and simple state machines with programmable intelligence. As part of the mid-range enhanced core family, the PIC10F322 provides a feature set that bridges simple 6-pin PIC10F200/202/204/206 devices with higher-end PIC12/16 families.
Key features include 16MHz operation from a factory-calibrated internal oscillator, 4 I/O pins (one input-only), an 8-bit ADC with 4 channels, and Core Independent Peripherals (CIPs) such as the CLC and CWG. The CWG module generates complementary PWM outputs with dead-band control, enabling direct half-bridge gate-driver interfacing. Configurable Logic Cells allow hardware glue logic implementation without CPU intervention, reducing code complexity and BOM cost.
Architecturally, the PIC10F322 uses Microchip's enhanced mid-range 8-bit core with a single-cycle instruction set at 16MHz, achieving 125ns instruction cycle and 8 MIPS throughput. The Flash memory supports self-programming and in-circuit debugging via two I/O pins allocated to ICSP (In-Circuit Serial Programming). Wide operating voltage from 2.3V to 5.5V supports both 3.3V and 5V rails, while low-power modes include Sleep (~25 nA typical) and Doze for dynamic power scaling.
Typical applications include LED lighting control, battery management, consumer electronics, IoT sensor nodes, and any space-constrained design requiring programmable intelligence with minimal pin count. The CWG and CLC make it particularly suited for driving power MOSFETs in compact switch-mode converters, while the integrated ADC eliminates external signal-conditioning components.
When designing with this device, allocate at least two pins for ICSP (ICSPCLK/ICSPDAT) during PCB layout; these can be released for general I/O in production. Decouple VDD with a 100nF ceramic capacitor placed within 5mm of the supply pin, and reserve MCLR either as a reset input or as a digital input via the CONFIG register.

Design Notes
Allocate ICSPCLK (RA1) and ICSPDAT (RA0) as dedicated programming pins during PCB layout. According to the Microchip PIC10F320/322 datasheet, these pins must be accessible for in-circuit serial programming; production code can reuse them as general I/O by clearing the appropriate CONFIG bits. Place a 100nF X7R ceramic bypass capacitor within 5mm of the VDD pin, using the shortest possible trace to the ground pad to minimize supply noise during ADC conversions.
Estimated: with a 3.3V supply and 16MHz active operation, the PIC10F322-I/MC draws approximately 1 mA typical current. In Sleep mode, consumption drops to ~25 nA typical. For battery-powered designs, duty-cycle aggressively; a 0.1% active time achieves average current of approximately 1 uA on a CR2032 coin cell (~240 mAh), yielding a theoretical battery life exceeding 25 years. Decouple VDD with both bulk (1uF) and high-frequency (100nF) capacitors placed in parallel.
Do not connect RA3/MCLR directly to VDD if external reset is unused - this prevents in-circuit programming access. Always configure MCLR via the CONFIG register as a digital input (RA3) for production use, or tie it through a 10k resistor to VDD for hardware reset. Also, ensure ADC input pins do not exceed VDD by more than 0.3V, as the absolute maximum ratings on analog inputs can permanently damage the device. Configure unused pins as outputs low to minimize current leakage.
The 8-pin DFN (2x3 mm) package has a center thermal/exposed pad that must be soldered to the PCB ground plane for mechanical reliability and thermal dissipation. According to the Microchip datasheet package specification, the DFN center pad should connect to a ground copper pour of at least 0.5 square inches with multiple thermal vias to the inner ground plane. Avoid routing signal traces beneath the package to prevent short-circuit risk during reflow.
When using the ADC for precision measurements, configure the A/D conversion clock to derive from FOSC/16 or slower to ensure adequate acquisition time. According to the Microchip datasheet, the ADC acquisition time must be at least 1.45 us at 16MHz FOSC to settle to 8-bit accuracy. Enable the ADC interrupt and avoid sampling during CWG transitions to prevent PWM-induced noise coupling into ADC readings.
Compliance Information
RoHS and REACH compliant per Microchip product declaration. AEC-Q100 qualification not applicable for standard PIC10F322-I/MC; choose PIC10F322-E/MC for extended temperature or automotive-grade PIC10F32X variants.
