MPLAB

ICD 2

18-PIN HEADERS

For these headers, there are no jumpers/switches. The device with the most program

memory is always selected.

If PIC16F627A or PIC16F628A devices are selected for MPLAB ICD 2 development in

MPLAB IDE, the warning “ICDWarn0020: Invalid target device id” may be received in

the build window and as a dialog. The reason is the PIC16F648A-ICD device supports

PIC16F648A, PIC16F627A and PIC16F628A, but only reports the device ID for the

PIC16F648A.

Ignore this warning or disable it under the Warnings tab on the ICD Programming

dialog.

20-PIN HEADER – PIC16F639

For the PIC16F639 20-pin header, you will need to connect the jumper J3 as specified

below.

In addition to being used with MPLAB ICD 2, this header is used with the PCM16YM0

processor module to emulate a PIC16F639 on the MPLAB ICE 2000 in-circuit emulator.

Plug the end of the processor module into the header, and then plug the header into

the transition socket or directly onto the target board.

20-PIN HEADER – PIC16F785

For the PIC16F785 20-pin header, you will need to connect the jumper J2 to enable the

shunt regulator.

20-PIN HEADER – PIC16F690

For the PIC16F690 20-pin header, you will need to set the S1 switches (Figure 2) to

enable peripherals and choose devices (Table 3).

Header Specification

64/80-PIN HEADERS

For these headers, there are no jumpers/switches. MPLAB IDE will use its selected

device to choose the correct device to emulate.

Test points are available on this header to check the following: V

DD, VDDcore and

ground.

The PICDEM™ HPC Explorer Board is 5V, whereas the ICD device on the header is

3.6V max. Therefore, modification to the demo board is necessary before the header

can be used.

1. Switch S3 should be set to ICE.

2. Jumper J2 must be connected as shown to modify the operating voltage. See

demo board documentation for more information.

Connect the Header and MPLAB ICD 2

Connect the 9-inch modular interface cable between the MPLAB ICD 2 Module and the

MPLAB ICD 2 Header.

Connect the Header and the Target Board

The header may be connected to the target board as follows:

• PDIP header socket to PDIP target socket with a stand-off (male-to-male

connector)

• Header socket to plug on the target board

• Header socket to target socket with a transition socket (see MPLAB

ICE

2000/4000 Transition Socket Specification, DS51194)

MPLAB

ICD 2

PROGRAMMING NON-ICD DEVICES

The MPLAB ICD 2 header can only program the -ICD device, not the regular device.

To program non-ICD devices with the MPLAB ICD 2, use the Universal Programming

Module (AC162049) or design a modular interface connector on the target. See the

appropriate specification for connections. For the most up-to-date device programming

specifications, see the Microchip website (www.microchip.com).

CALIBRATION BITS

The calibration bits for the band gap and internal oscillator are always preserved by the

MPLAB ICD 2 to their factory settings.

MPLAB ICD 2 PERFORMANCE

The PICmicro

MCU devices do not support partial program memory erase; therefore,

users may experience slower MPLAB ICD 2 performance than with other devices.

ADDITIONAL INFORMATION

Please refer to the MPLAB

ICD 2 In-Circuit Debugger User’s Guide (DS51331),

MPLAB IDE Help and the MPLAB ICD 2 Readme for additional information.
