Microchip Technology DAF30-2

Overview

DAF30-2 from Microchip Technology is a device adapter for the MPLAB® ICE 4000 in-circuit emulator system, designed to interface with 64/80-pin TQFP and 68/84-pin PLCC microcontrollers. It provides mechanical and electrical compatibility between the emulator pod and target boards, includes on-board oscillator circuitry for accurate clock emulation, and supports serial EEPROM-based auto-configuration in MPLAB IDE. It is used during firmware development and debug of PICmicro and dsPIC devices.

For engineers reviewing the DAF30-2 datasheet, DAF30-2 pinout, DAF30-2 application, or DAF30-2 equivalent, this page delivers verified mechanical dimensions, supported package mappings, target footprint specifications, ESD-safe handling guidance, and integration requirements with MPLAB ICE 4000 processor modules and transition sockets.

Technical Context

The DAF30-2 implements a passive, socket-based interface with no active logic or power regulation. Its core function is physical translation: mapping PLCC pin 1 (y-location) and TQFP pin 1 (x-location) to the emulator's flex-circuit cable interface while preserving signal integrity for emulation signals including VCCME, GND, OSC1, OSC2, and I/O lines.

It integrates a dedicated oscillator circuit to emulate the target MCU's oscillator characteristics - supporting HS, XT, LP, LF, and RC modes - with 5 pF–10 pF capacitive loading on OSC1/OSC2. The onboard serial EEPROM stores adapter type and revision data for automatic recognition by MPLAB IDE, eliminating manual jumper or switch configuration.

FAQ

What is the DAF30-2 used for in the MPLAB ICE 4000 system?

The DAF30-2 is a device adapter that physically and electrically bridges the MPLAB ICE 4000 emulator pod to target boards using 64/80-pin TQFP or 68/84-pin PLCC microcontrollers. It enables in-circuit debugging by providing correct pin mapping, oscillator emulation, and auto-configuration via onboard EEPROM - all essential for reliable firmware development with the DAF30-2.

Which microcontroller families does the DAF30-2 support?

The DAF30-2 supports PICmicro and dsPIC microcontrollers packaged in 64/80-pin TQFP or 68/84-pin PLCC formats. Specific device compatibility is defined in the "Readme for MPLAB ICE 4000.txt" file shipped with MPLAB IDE - the DAF30-2 itself does not contain logic or firmware and relies on software-defined device mapping.

Does the DAF30-2 require external power or generate its own?

The DAF30-2 is a passive adapter with no internal power regulation or generation. It draws minimal current from the target board (e.g., for the oscillator circuit and EEPROM), and its operation depends entirely on either emulator-supplied or target-supplied power - as configured in MPLAB IDE. The DAF30-2 does not regulate or convert voltage.

How does the DAF30-2 handle oscillator emulation for different modes (HS, XT, RC)?

The DAF30-2 includes an on-board oscillator circuit that emulates the target MCU's oscillator behavior across HS, XT, LP, LF, and RC modes. OSC1 and OSC2 present 5 pF–10 pF load capacitance; for RC mode, actual frequency may vary due to emulator circuitry - users must adjust RC values or use the emulator's internal clock source to achieve precise timing with the DAF30-2.

Can the DAF30-2 be used without a transition socket?

Yes - the DAF30-2 is designed for direct solder-down onto target PCBs using its standardized footprint (2.600″ × 2.950″), compatible with Samtec DWM 0.050″ pitch stackers. This eliminates need for transition sockets during development or production debug, provided the target board layout matches the DAF30-2 mechanical drawing per DS51298E-page 6.
