Intel i8035 Processor Replacement
The venerable i8035 has
been available since the 1970s, predates the somewhat more popular i8051
processor, and though still available through grey-market, is getting
harder to find. The i8035 retrofit module will plug directly into an 8035
processor footprint, permitting a skilled programmer to regenerate the application
for the PIC processor. The programming header will permit interfacing to
a PC via the Microchip ICD2, allowing USB connectivity and live in-system
debugging. With minimal expense, the new application can be developed,
and any existing installations can continue to use the existing original
The unit has the following feature set:
- PIC16F877A processor, though in production any PIC in a 44-pin TQFP package may be substituted per customer requirement.
- 20MHz operating frequency, though as above, any crystal (<20MHz) may be substituted in modest production runs.
- Pull-up resistors to simulate the intel style of output driver (either driven low or converted to input with internal pull-up).
- Programming header to permit connection to an ICD2 or other in-circuit programmer.
- Available pre-programmed with your application as required.
- Intel 8035 processor footprint.
- 5V operating voltage.
- 2.1"x0.9" overall dimensions.
For in-system code development, an in-circuit debugger or emulator may be used.
The Microchip ICD2 will connect directly to the module, however due to space limitations on
the module itself, a custom header has been used. As a result, a custom programming cable is required, also
available from J-Tech.
