PIC16F506T-I/MG - 8-bit MCU 1.5KB Flash 20MHz QFN-16 | Microchip
MPN： PIC16F506T-I/MG ✓ 啟用中PIC16F506T-I/MG 概覽
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path that fetches, decodes, and executes instructions from on-chip program memory. The PIC16F family sits in the larger product taxonomy: microcontroller -> embedded controller -> semiconductor device. PIC cores use a modified Harvard RISC architecture with 12-bit wide instructions optimized for code density, and the PIC16F506 uses a 14-bit instruction word typical of midrange PIC16 devices, balancing speed and program memory efficiency.
Key features include 1.5KB self-programmable Flash for in-circuit serialization, low-power operation with nanoWatt technology (typical 100 nA standby), wide operating voltage (2.0V to 5.5V), and an integrated 4-channel 8-bit ADC. The device supports in-circuit debugging via ICD and includes a Watchdog Timer with on-chip, low-power RC oscillator for safety-critical recovery.
Typical applications include remote controls, consumer appliances, LED lighting controllers, battery-powered handheld devices, security sensors, and small motor control. The 16-QFN package's 3x3 mm footprint and low pin count suit cost-sensitive, high-volume designs where every square millimeter of PCB matters.
Designers should configure unused I/O pins as outputs and tie them low to minimize power consumption. The exposed thermal pad of the QFN package must be soldered to a ground pad on the PCB for both thermal dissipation and electrical performance, and an MPLAB ICD programmer/debugger should be reserved in the design for firmware iteration.
This page consolidates distributor pricing, pin-compatible Microchip drop-in alternatives, and practical design guidance not found in the standalone manufacturer datasheet, helping engineers evaluate PIC16F506 variants in a single comparison view.

典型應用
PIC16F506T-I/MG 適用於 6 應用s: Remote Controls (IR/RF), Consumer Appliance Control, LED Lighting Controllers, Security and PIR Sensors, Battery-Powered Handheld Devices, Industrial Sensor Modules.
Remote Controls (IR/RF)
PIC16F506T-I/MG powers cost-optimized IR/RF remote controls thanks to its 1.5 KB Flash for state machines and button-scan routines, 67-byte RAM for buffer storage, and nanoWatt sleep currents below 100 nA that preserve coin-cell life for years. The 12 I/O drive keypad matrix, IR LED modulator, and status LEDs without external logic, while the 16-QFN 3x3 mm footprint keeps the PCB small enough for slim handset enclosures. Real-world designs pair it with a 32 kHz crystal or internal LFINTOSC for low-power standby with sub-1 uA average draw, supporting multi-year battery operation.
推薦
Consumer Appliance Control
The PIC16F506T-I/MG drives small kitchen and personal-care appliances such as coffee grinders, blenders, and toothbrush chargers where its 1.5 KB Flash, 12 I/Os, and integrated 4-channel 8-bit ADC handle motor PWM, button inputs, and battery or line-voltage sensing. Wide 2.0-5.5 V operation supports both battery and rectified mains dropper supplies. The 20 MHz / 5 MIPS throughput allows 50 kHz PWM frequencies for quiet BLDC commutation while leaving cycles for safety watchdogs.
推薦
LED Lighting Controllers
Lighting controllers for signage, accent strips, and decorative luminaires benefit from the PIC16F506T-I/MG's 1.5 KB Flash to drive multi-channel PWM dimming, its 4-channel 8-bit ADC for ambient-light feedback, and its 12 I/Os to manage serial or DMX-like LED protocols. Operating from 2.0-5.5 V lets the same firmware run from 3.3 V logic supplies or 5 V USB rails. Integrated LFINTOSC reduces BOM cost in space-constrained light fixtures.
推薦
Security and PIR Sensors
PIR motion sensors and wireless alarm peripherals use the PIC16F506T-I/MG to run duty-cycled sampling loops at very low average current, with the on-chip 31 kHz LFINTOSC enabling microamp sleep modes between ADC samples. Its 4-channel ADC reads the PIR analog output, temperature compensation, and battery voltage, while 12 I/Os drive an LED indicator, alarm relay, and a low-power RF transmitter. The 16-QFN keeps the module footprint small enough for in-ceiling mounting.
推薦
Battery-Powered Handheld Devices
Handheld toys, fitness bands, and remote key fobs benefit from PIC16F506T-I/MG's nanoWatt standby (typical 100 nA), 2.0-5.5 V supply, and tiny 3x3 mm QFN that fits inside miniature enclosures. The integrated 4/8/16 MHz oscillator eliminates external crystals, shrinking BOM to MCU + decoupling caps + battery holder. Firmware fits within 1.5 KB for read-button, drive-LED, and PWM-vibrate routines typical of these products.
推薦
Industrial Sensor Modules
Industrial 4-20 mA loop-powered sensors and discrete process switches use PIC16F506T-I/MG to digitize analog inputs via its 4-channel 8-bit ADC, drive HART or Modbus RTU via software UART on spare I/Os, and survive -40C to +85C environments thanks to industrial-grade qualification. The 20 MHz instruction rate completes one ADC-to-output cycle in under 200 us while leaving headroom for a watchdog safety routine on the same 12 I/Os.

主要差異化特點
- NanoWatt technology with sub-100 nA standby current (對比PIC16F505T-I/MG)
- 12 I/O in a 3x3 mm QFN footprint (對比PIC16F506-I/P (DIP-14))
- Industrial temperature grade (-40C to +85C) (對比PIC16F506-E/MG (extended grade))
設計說明
The PIC16F506T-I/MG QFN-16 has an exposed thermal pad (EP) on the underside that serves as the primary electrical ground and thermal path. Solder this pad to a PCB ground plane of at least 5x5 mm copper for proper thermal dissipation. Per the Microchip datasheet, missing or undersized EP soldering leads to higher junction temperatures and reduced operating reliability. Use a 0.1 uF ceramic bypass cap within 3 mm of the VDD pin.
GP3 is an input-only pin in the PIC16F506 family - configuring it as an output has no effect and may damage the silicon. Reserve GP0 and GP1 for ICSP programming/debug during bring-up; routing them to permanent external circuitry can make firmware update difficult. The MCLR function shared with GP3 must be pulled high through a 10 kohm resistor for normal operation, and a push-button can be added for manual reset without affecting ICSP.
Estimated: enabling Sleep mode with LFINTOSC at 31 kHz and waking via Watchdog Timer every 4 seconds yields average current of approximately 5-10 uA in a typical sensor application. The PIC16F506 nanoWatt technology keeps standby current at ~100 nA when properly configured, so most of the budget is consumed by peripherals. Use Configuration bits to disable unused modules (ADC, comparators) for further savings.
