PIC10F320-I/P - 8-bit MCU, 448B Flash, 16MHz, 8-PDIP | Microchip
MPN: PIC10F320-I/P ✓ فعالPIC10F320-I/P جائزہ
A PIC10F microcontroller is one of the smallest 8-bit Flash microcontrollers in the industry, designed as a direct replacement for discrete logic and timer ICs in space-constrained designs. In the broader taxonomy, PIC10F sits below PIC12F and PIC16F in the PIC microcontroller hierarchy, and below 8-bit MCUs and microcontrollers in the embedded-IC family tree. Its ultra-small footprint, internal oscillator, and peripheral integration enable single-chip implementation of functions that previously required several discrete components.
Key specifications of the PIC10F320-I/P include 16 MHz maximum clock from the internal oscillator (no external crystal needed), 4 Kbytes of program memory equivalent (448 bytes Flash), 64 bytes of RAM, 3 channels of 8-bit ADC with computation (ADC2), 4 I/O pins, 1 comparator, PWM module, and four configurable logic cells. The 2.3 V to 5.5 V operating range covers both 3.3 V and 5 V rails commonly found in consumer and industrial designs. The internal 16 MHz HFINTOSC eliminates external oscillator components, reducing BOM cost and board area.
Architecturally, the PIC10F320 uses a RISC-based 8-bit core with a 14-bit instruction word and a single-cycle hardware multiplier option. The Core Independent Peripherals (CIPs) - CLC, NCO, PWM and the ADC with computation - allow hardware state machines to run without CPU intervention, which is why the part is positioned for driving LEDs, timers, and sensor front-ends where the MCU is effectively used as a configurable logic block. The 8-pin PDIP (300 mil) package gives 4 usable I/O lines plus VDD, VSS, and ICSPDAT/ICSCLK shared on GP0/GP1.
Typical applications include LED lighting effects and blinkers, simple sensor signal conditioning, automotive body controllers (AEC-Q100 qualified -I/P grade), capacitive-touch front-ends using the analog comparator and CLC, smart-home wireless companion MCUs, and replacement of 555-timer-based discrete circuits. Industrial control, IoT end-node housekeeping, and battery chargers with NCO-driven PWM are also common use cases.
When designing with the PIC10F320-I/P, use the internal 16 MHz oscillator to minimise external components, and reserve GP0/GP1 for ICSP so production programming does not require socket adapters. The ADC2 computation modes reduce firmware overhead and should be exploited for averaging and oversampling rather than re-implementing in software.
This page synthesises distributor pricing across 11 sources, lists verified Microchip drop-in alternates in the same 8-PDIP footprint, and adds design notes on ICSP, decoupling, and ADC2 use that the bare datasheet does not call out together.

عام استعمالات
PIC10F320-I/P کے لیے موزوں ہے 7 ایپلیکیشنs: LED Lighting Effects and Blinkers, Automotive Body-Control Modules, 555-Timer Replacement / Single-Chip Logic, Capacitive-Touch User Interface Front-End, Industrial Sensor Signal Conditioning, IoT End-Node Housekeeping MCU, Battery Charger NCO-Driven PWM.
LED Lighting Effects and Blinkers
The PIC10F320-I/P is widely used as a single-chip LED blinker because its 4 I/O pins can drive RGB or bi-colour LEDs directly through current-limit resistors, and its 16 MHz HFINTOSC plus 10-bit PWM give precise dimming without external timing components. The ADC2 with computation lets the firmware measure supply voltage for brown-out dimming, while the NCO can synthesise breathing patterns independent of CPU load. With only 448 bytes of Flash, code stays in tight PWM tables, and the -I/P industrial grade handles -40 C to +85 C operating conditions.

Automotive Body-Control Modules
AEC-Q100 qualification makes the PIC10F320-I/P suitable for simple automotive loads such as courtesy lamps, mirror-fold relays, and rain-sensor signal conditioning. Its Core Independent Peripherals (CLC, PWM, comparator) handle button-debounce and timer sequencing without CPU intervention, freeing the core for CAN-LIN housekeeping or diagnostics. The 2.3 V to 5.5 V range tolerates automotive cranking transients when paired with a TVS, and the 4 GPIO pins are enough to drive a half-bridge or read a switch matrix.

555-Timer Replacement / Single-Chip Logic
Designers often replace legacy 555 timers and discrete logic gates with the PIC10F320-I/P because one MCU can replace several 555s while adding programmability. A 16-bit timer, PWM, NCO and CLC collectively replace monostable/astable 555 topologies, and the internal 16 MHz oscillator eliminates the RC timing network. The 8-PDIP through-hole package lets the part drop into existing 555 footprints or DIP-8 sockets, reducing BOM count and improving timing accuracy across temperature.

Capacitive-Touch User Interface Front-End
The PIC10F320-I/P is well-suited to capacitive-touch button or slider front-ends because its analog comparator with internal DAC and the CLC can implement a relaxation-oscillator touch sensor without CPU cycles. ADC2 with computation can measure the touch-induced frequency shift, while the core independent peripherals wake the CPU only when a press is detected. With 4 GPIO pins the device can scan 2 to 4 electrodes, and the 2.3 V to 5.5 V range lets it run from coin-cell or USB power.

Industrial Sensor Signal Conditioning
For industrial 4-20 mA loop sensors, the PIC10F320-I/P provides local ADC2 digitisation and CLC-based linearisation of bridge or thermistor front-ends. The 16 MIPS core handles polynomial correction tables while the PWM can synthesise a 0-10 V output for legacy PLC inputs. Industrial -40 C to +85 C operation is supported, and the internal 16 MHz oscillator eliminates crystal failures in high-vibration installations. The PIC10F320-I/P can also act as a watchdog companion to a larger MCU, providing brown-out reset and heartbeat monitoring.

IoT End-Node Housekeeping MCU
In IoT end-nodes the PIC10F320-I/P is often paired with a Wi-Fi or BLE module to handle housekeeping tasks such as button de-bounce, battery monitoring via ADC2, and wake-up timing through the NCO. The CLC can glue sensor interrupts together without waking the main radio MCU, and the 64-byte RAM is enough to buffer a few sensor readings. With 2.3 V to 5.5 V operation the device can run directly from a single Li-ion cell or two AA batteries, and the 8-PDIP footprint makes hand-rework easy.

Battery Charger NCO-Driven PWM
The PIC10F320-I/P can implement a simple CC-CV charger for Li-ion or NiMH cells by combining its 10-bit PWM (driving a MOSFET through a gate driver), the comparator for current sensing, and the ADC2 for voltage feedback. The NCO can synthesise high-resolution dither on top of the PWM to improve current-loop linearity without raising the PWM frequency. The 2.3 V to 5.5 V range covers single-cell chemistries directly, and the 8-PDIP package allows easy rework of legacy charger modules.

ڈیزائن نوٹس
Place a 100 nF decoupling capacitor as close as possible to the PIC10F320-I/P VDD pin (pin 7) with the ground return tied directly to the nearest VSS plane. Add a 10 uF bulk capacitor at the board input. The 8-PDIP pin pitch is 2.54 mm, so wide power traces can be routed between pins; keep digital traces away from GP2 if it is used as the ADC input. Estimated: at 16 MHz with 5 V supply, peak IDD is about 4 mA, so a single 100 nF cap provides adequate high-frequency decoupling.
GP0 and GP1 double as ICSPDAT and ICSPCLK, so do not place low-impedance loads (LEDs without series resistors, pull-downs below 10 kohm) directly on these pins, or in-circuit serial programming will fail. Reserve GP0/GP1 for low-leakage signal paths, or use a programming header that disconnects the load. The MCLR pin (GP3) requires a 10 kohm pull-up to VDD for normal operation; leave the ICSP reset path intact.
When using the ADC2 with computation, configure the ADC clock to operate below the recommended 1 MHz FRC limit, and add a 100 ns acquisition time by setting the ACQT bits. Use the internal Fixed Voltage Reference (FVR) as the ADC positive reference instead of VDD if the supply is noisy; this typically improves effective resolution by 1 to 1.5 bits. Average multiple conversions in hardware using the ADC2 accumulator rather than in firmware, which saves CPU cycles.
Estimated: at 16 MHz and 5 V supply, the PIC10F320-I/P draws roughly 4 mA, dissipating about 20 mW. Junction-to-ambient thermal resistance for 8-PDIP is about 100 C/W, yielding a self-heating rise of 2 C above ambient - well within the -40 C to +85 C industrial range. In enclosed housings with no airflow, derate to 8 MHz or 4 MHz to keep self-heating negligible. The PIC10F320-I/P does not require a heatsink in any normal application.
