PIC16LC620A-04E/SS Présentation
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory, and peripherals on one die. The PIC16C/LC family uses a Harvard RISC architecture with separate program and data buses, enabling single-cycle instruction execution (200 ns at 20 MHz). Within the broader hierarchy, this part sits as: 8-bit MCU -> RISC microcontroller -> embedded controller -> semiconductor IC. The 'LC' subfamily denotes the low-voltage (2.5-6.25 V) range, while 'C' versions require 4.5-5.5 V; engineers select the LC variant for battery-powered or 3.3 V-only systems.
Key features of the PIC16LC620A-04E/SS include 12-bit wide instructions with 8-bit wide data path, seven or eight special function hardware registers, two-level deep hardware stack, and direct/indirect/relative addressing modes. The '04' speed grade denotes a 4 MHz maximum oscillator, while the 'E' suffix indicates the Extended industrial temperature range (-40C to +125C). The OTP program memory uses EPROM cells that can be programmed once with a standard device programmer (e.g., MPLAB PM3).
Typical applications include automotive body controllers (under-hood and cabin modules), industrial sensor interfaces, consumer appliance control boards, low-power remote sensor nodes, and replacement of legacy 8051 designs where a smaller code footprint is needed. The 13 I/O pins can drive LED indicators, read push-buttons, interface to UART peripherals, and bit-bang simple serial protocols.
When designing with this part, ensure your programmer supports OTP EPROM devices and budget for in-circuit emulation during development. The PIC16LC620A has been superseded by flash-based PIC16F equivalents (e.g., PIC16F636) for new designs, but remains in production for long-lifecycle automotive and industrial customers.

Applications typiques
PIC16LC620A-04E/SS convient pour 7 applications: Automotive Body Control Modules, Industrial Sensor Signal Conditioning, Consumer Appliance Control Boards, Battery-Powered Remote Sensor Nodes, White Goods User Interface Panels, Legacy 8051 Replacement, LED Lighting Control Modules.
Automotive Body Control Modules
The PIC16LC620A-04E/SS Extended temperature grade (-40C to +125C) and OTP program memory make it ideal for under-hood automotive body controllers, climate control panels, and instrument cluster sub-assemblies. With 13 I/O pins the MCU can scan a 4x4 keypad matrix, drive LED indicators for HVAC feedback, and bit-bang a LIN slave interface to a body control gateway. The 2.5-6.25V supply range tolerates automotive load-dump transients when paired with a TVS diode and bulk capacitor. Its 896B EPROM holds typical HVAC state-machine code in 400-500 instructions, leaving headroom for diagnostics.
Recommandé
Industrial Sensor Signal Conditioning
The PIC16LC620A-04E/SS is well suited to industrial 4-20 mA loop-powered sensor transmitters and bridge sensor signal conditioners. Its analog comparator peripheral, paired with the internal voltage reference, digitizes RTD or strain-gauge signals without an external ADC. The 2-level hardware stack and 35-instruction RISC core execute PID loops in under 100 microseconds per iteration, sufficient for thermal or pressure control. Wide 2.5-6.25V supply directly interfaces to 24V industrial loops after a Zener-regulated shunt regulator.
Recommandé
Consumer Appliance Control Boards
The PIC16LC620A-04E/SS powers entry-level consumer appliance control boards such as microwave oven keypads, washing-machine user interfaces, dishwasher control panels, and rice cooker timers. Its 13 I/O lines directly drive 7-segment LED displays through current-limit resistors and scan a 3x4 matrix keypad without external logic. The 896B OTP memory holds the appliance state machine and timer code in roughly 500 instructions. The Extended temperature grade survives the under-counter thermal environment of kitchen appliances.
Recommandé
Battery-Powered Remote Sensor Nodes
The PIC16LC620A-04E/SS supports battery-powered remote sensor nodes operating from a 3V coin cell or two AA cells, thanks to its low-voltage 2.5V minimum supply and low operating current. The integrated watchdog timer and sleep mode (via software) extend battery life to multi-year durations in duty-cycled wireless sensor applications. With 13 I/O pins the MCU can interface to a sub-GHz radio module (e.g., CC1101) via SPI bit-bang, read temperature/humidity sensors, and drive an LED status indicator. The 4 MHz internal oscillator eliminates the need for an external crystal in cost-sensitive designs.
Recommandé
White Goods User Interface Panels
The PIC16LC620A-04E/SS is widely deployed in white-goods user-interface panels including refrigerator temperature controllers, dishwasher cycle selectors, and oven timer displays. The Extended temperature rating handles the thermal stress of under-counter and behind-panel mounting locations. The 35-instruction RISC core executes button debouncing and seven-segment multiplex code in a tight 200ns instruction cycle, allowing fully interrupt-driven user-interface firmware. Its 96 bytes of RAM support a 4-digit display buffer plus push-button state.
Recommandé
Legacy 8051 Replacement
Engineers replacing legacy 8051 microcontrollers in industrial controllers and consumer devices often select the PIC16LC620A-04E/SS as a drop-in upgrade path. Its Harvard RISC architecture executes instructions 4x faster than the 8051 at the same clock speed, reducing EMI by allowing operation at a lower clock frequency. The 35-instruction RISC core is faster to learn and produces tighter assembly code than the 8051's 256-opcode CISC set. The PIC16LC620A-04E/SS occupies the same 20-SSOP footprint area as a typical 20-pin 8051, simplifying PCB reuse.
Recommandé
LED Lighting Control Modules
The PIC16LC620A-04E/SS serves as a cost-optimized controller for entry-level LED lighting modules, decorative light strings, and architectural dimmers. Its 13 I/O pins can drive multiple MOSFET gates for RGBW LED channels via PWM generated in firmware. The 4 MHz oscillator provides 200 ns timing resolution, suitable for 8-bit PWM dimming at refresh rates above 1 kHz. The 2.5-6.25V supply range directly interfaces to 5V LED driver rails without additional regulation.

Principaux différenciateurs
- Extended -40C to +125C temperature grade vs industrial -40C to +85C (vs PIC16LC620A-04I/SS)
- 20-SSOP compact footprint vs 18-pin SOIC/PDIP (vs PIC16LC620A-04E/SO)
- Low-voltage 2.5V operation vs 4.5V minimum (vs PIC16C620A-04E/SS)
Notes de conception
Decouple VDD (pin 20) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a 10 uF tantalum bulk capacitor on the supply rail. The PIC16LC620A-04E/SS draws up to 5 mA active at 4 MHz; using a low-Iq LDO such as MCP1700 (1.6 uA quiescent) keeps sleep current below 1 uA for battery-powered designs. The VSS pin (pin 19) must connect to a solid ground plane to minimize EMI.
Route the OSC1/OSC2 traces (pins 16/15) as short as possible and keep them away from switching signals. For crystal operation, place the 22-33 pF load capacitors within 3 mm of the oscillator pins. If using the internal 4 MHz RC oscillator, leave OSC1 floating or tie to VDD through a 10 kohm resistor, and OSC2 can be left open or used as CLKOUT. The MCLR pin (pin 4) requires a 10 kohm pull-up to VDD for normal operation.
Do not exceed 6.25 V on VDD; the absolute maximum is 7 V but operation above 6.25 V violates datasheet specs. The OTP EPROM can be programmed only once via VPP on the MCLR pin - use MPLAB PM3 or compatible programmer. The 2-level hardware stack means C compilers (e.g., MPLAB XC8) must use careful stack depth management for deeply nested function calls. For new designs, prefer flash-based PIC16F636-I/SS to allow field reprogrammability.
