Device: MPF300T [ISP Mode]
- Manufacturer(s): Microchip
- Device type: PLD, PAL, EPLD
Microchip MPF300T [ISP Mode] is programmed "in-system", i.e. being installed on a board. The matrix below lists Phyton device programmers that support the MPF300T [ISP Mode] device in-system programming and appropriate cable-Adapters or device library licenses.
| MPF300T [ISP Mode] is programmed by | ||
|---|---|---|
| Connection or Adapter | Device programmers | Required license |
| Connection diagrams | CPI2-B1-x (preloaded) | CPI2-D-MCPLD device library license is required |
Recommended CPI2-B1&CPI2-Gx connection (AE-ISP-ARM-2 connection for Devices via 4-wire JTAG + Reset)
Powering the target device:
There are two alternative options for powering the targets:
1. The target gets power from the programmer (Vdd). This is possible only if the target does not consume too much energy. A capacity of the target power circuitry should not exceed 50 uF.
2. The target gets power from a built-in or external power supply. In this case the power output from the programmer should not be connected with the target. The target system should be tolerant to applying logical signals with the voltage levels exceeding the voltages on the target.
NOTE! It is strictly prohibited to power the target from both the programmer and built-in or external power supply simultaneously.
Isolating resistors:
Purpose of the R1..R6 resistors is to isolate the programmed chip from rest of target system. Recommended value of resistors R1..R6 is 2k or more. You can also use jumpers instead of the resistors.
ISP characteristics:
1. Programmer''s output capability:
1.1 Vcc - 80 mA;
1.2 Vpp - 50 mA;
1.3 logical pins - 5 mA.
2. The cable length should be less then one foot.
