Hi antedeluvian
Thanks for the help. Yes, it is a 0.3" wide 28-pin DIP. The pinouts don't match any chip from Atmel, Microchip, Freescale, Philips or ST, and from the info you provided it seems to be a Cypress PSoC chip.
Hi polymath
Your suggestion about the 28-pin module board is a good idea...
28pin 8051
The customer has a few faulty units in which all circuit seems to be OK except the microcontroller. In order to get them working again, he wants to replace the faulty micros by a new one. The company from where he purchased the instruments has closed down. So no support is available...
identify microcontroller

There is no external crystal. VDD is 5 V.
The pinouts don't seem to match any of the PIC or AVR devices.
Any help in identification will be appreciated.
28 pin microcontroller
Hi all,
I got an assignment to develop program for a 28-pin DIP type package microcontroller. The hardware is already designed and assembled but the microcontroller is damaged.
The number on microcontroller has been scraped off. Only info about microcontroller I could...
rf modules serial
Munib wrote in original message:
I believe the problem is being caused by the output device in transmitter or input device in receiver going into saturation when a 0 is sent ( transistor is switched on for a 0 ) and it takes time to come out of saturation when the first 1 is...
microcontroller ic for noisy and emi environment
Thanks IanP for providing link to Maxim's microcontroller info. It seems to be a good microcontroller.
I understand that it has an option of switching off ALE, when not needed, to reduce noise emissions.
However, I want to know, how good is it...
how shielding to reduce noise for microcontroller
Hi all,
I need a microcontroller with following features for an industrial control project:
- Flash memory > 32 K bytes
- 2 UARTs
- 1 synchronous serial port such as SPI
- support for external RAM interface
- 5V supply voltage
- excellent...
