Product details
Overview
DV164121 from Microchip Technology is a PICkit™ 2 Programmer/Debugger development tool designed for in-circuit programming and debugging of Flash-based PIC® microcontrollers and serial EEPROM devices via ICSP™ interface. It supports USB 2.0 connectivity, delivers target VDD from 2.5V to 6.5V, features three status LEDs (Power/Green, Target/Yellow, Busy/Red), and includes a 6-pin ICSP programming header with VPP/MCLR, VDD, VSS, PGD, PGC, and Auxiliary pins.
For engineers reviewing the DV164121 datasheet, DV164121 pinout, DV164121 application, or DV164121 equivalent, this tool serves as a low-cost, field-deployable development interface for firmware iteration, memory read/write/verify/erase, code protection enablement, OSCCAL calibration, UART terminal emulation, and MPLAB IDE integration - all without requiring external power supplies or complex setup.
Technical Context
The DV164121 implements In-Circuit Serial Programming™ (ICSP™) using a dedicated 6-pin header with defined signal roles: VPP/MCLR for reset and programming voltage, PGD/ICSPDAT for bidirectional data, and PGC/ICSPCLK for synchronous clocking. It operates as a USB HID-class device with embedded firmware that handles protocol translation between host PC commands and target MCU programming sequences.
It supports auto-detect, forced-PICkit, or forced-target VDD sourcing modes; enables fast or slowed ICSP communication for loaded lines; and provides hardware-level UART bridging functionality via its same physical connector - allowing real-time serial communication with USART-equipped PIC MCUs without additional adapters.

FAQ
What is the primary function of the DV164121?
The DV164121 is a PICkit™ 2 Programmer/Debugger used to program and debug Flash-based PIC® microcontrollers and serial EEPROM devices via In-Circuit Serial Programming™ (ICSP™). It connects to a host PC via USB and interfaces directly with target hardware using a standardized 6-pin header. The DV164121 supports memory read/write/verify/erase, code/data protection, OSCCAL calibration, and UART terminal functionality - all within a single compact unit.
Does the DV164121 require external power to operate?
No, the DV164121 draws operating power exclusively from the USB port (5V). It can optionally supply regulated target VDD from 2.5V to 6.5V to the connected microcontroller, eliminating the need for an external power supply during development. Target power mode is configurable as auto-detect, force-PICkit, or force-target in the DV164121 Programmer application.
Which microcontroller families are supported by the DV164121?
The DV164121 supports most Flash-based PIC® microcontrollers including Baseline (12-bit), Mid-Range (14-bit), Enhanced Mid-Range, PIC18, and dsPIC® DSC families, plus serial EEPROM and KeeLoq® HCS devices. Specific device compatibility is maintained in the DV164121's internal device file database, which can be updated via software to add new device support without hardware changes.
Can the DV164121 be used for debugging, or only programming?
Yes, the DV164121 supports hardware-assisted debugging for select PIC MCUs through PICkit 2 Debug Express mode, integrated with MPLAB IDE. This allows breakpoints, single-stepping, register inspection, and memory viewing during runtime. Debug capability depends on both the target device's debug architecture and correct configuration of the DV164121 firmware and host software - not all PIC devices are debug-enabled.
How is firmware updated on the DV164121?
Firmware on the DV164121 is updated via USB using the built-in bootloader. Pressing the front-panel push button while connecting USB places the DV164121 into bootloader mode. The PICkit 2 Programmer application or MPLAB IDE then downloads the latest OS image. Updates preserve user settings like calibrated VDD values and assigned Unit IDs, ensuring consistent operation across firmware versions.
