Microchip Technology TPG1LG01

Overview

TPG1LG01 from CCS is a handheld in-circuit programmer supporting PIC10, PIC12, PIC14, PIC16, PIC18, PIC24, and dsPIC microcontroller families; powered by four AA batteries, USB, or 9V AC adapter; stores up to four firmware images for field programming.

For engineers reviewing the TPG1LG01 datasheet, TPG1LG01 pinout, TPG1LG01 application, or TPG1LG01 equivalent, this tool enables portable, battery-operated ICSP programming without host PC dependency-critical for field firmware updates, production line reprogramming, and embedded system maintenance.

Technical Context

The TPG1LG01 implements ICSP™ (In-Circuit Serial Programming) protocol compliant with Microchip's standard programming interface, using dedicated VPP, PGD, PGC, VDD, and GND signals. It operates across 2.5–5.5V target supply range and supports both low-voltage and high-voltage programming modes.

Its internal flash memory stores up to four independent hex files, each selectable via front-panel buttons; firmware update is performed through CCS IDE over USB or via SD card (not included), with real-time progress feedback on integrated LCD.

Key Specifications

Manufacturer

CCS Inc. is a U.S.-based third-party tools provider specializing in development ecosystems for Microchip PIC® and dsPIC® microcontrollers since 1992.

The Load-n-Go product line was designed to deliver rugged, battery-powered, standalone ICSP programming for technicians and field engineers needing reliable firmware deployment outside lab or factory bench environments.

FAQ

What microcontroller families does the TPG1LG01 support?

The TPG1LG01 supports PIC10, PIC12, PIC14, PIC16, PIC18, PIC24, and dsPIC microcontroller families via standard ICSP™ protocol. It is validated against Microchip's DS41290 and DS41390 programming specifications and requires no additional adapters for these devices. The TPG1LG01 handles both low-voltage and high-voltage programming modes natively.

Can the TPG1LG01 operate without a PC or laptop?

Yes, the TPG1LG01 is fully standalone: it runs on four AA batteries and stores up to four firmware images internally. Users select and program targets using only its front-panel buttons and LCD display-no host PC, USB connection, or external software is required for field execution. The TPG1LG01 retains full functionality even when disconnected from USB or AC power.

How is firmware loaded onto the TPG1LG01?

Firmware is loaded onto the TPG1LG01 using the CCS IDE compiler suite via USB connection, or optionally via SD card (not included). Each of the four internal slots accepts standard Intel HEX files compiled for supported Microchip MCUs. The TPG1LG01 does not require proprietary file formats or conversion utilities.

Does the TPG1LG01 support high-voltage programming (HVP)?

Yes, the TPG1LG01 supports both low-voltage programming (LVP) and high-voltage programming (HVP) modes as defined in Microchip's ICSP specification. It automatically detects and applies appropriate VPP voltage (≈13V for HVP) when required by the target device configuration bits. This ensures compatibility with legacy and newer PIC devices alike.

What power options are available for the TPG1LG01?

The TPG1LG01 accepts three independent power sources: four AA batteries (3.6–6.0V), USB 5V, or an external 9V AC adapter. Battery operation enables true portability, while USB and AC power allow continuous use in bench or production settings. Power source selection is automatic and seamless-no manual switching is required.
