Overview

The PCA7408 is a PROM programming adapter for 7200 Series of Renesas 8-bit MCUs with internal PROM. The adapter is used to write programs using a commercially available PROM programmer for the M5M27C101 or equivalent.

Programmer Requirements

  • Programmable M5M27C101 or equivalent (Programming voltage: 12.5V)
  • Programming, verifying and erase check in specified area
  • 5V power supply (Approx. 10mA)
  • No device recognition code (Able to specify conditions directly)
  • Recommended: R4944A, R4945 (ADVANTEST CORPORATION)

Components

  • Main unit (PCA7408)
    A board with an IC socket for the MCU package
  • Connector (PCA7476E)
    A board for connecting to a PROM programmer. Pins for a 32-pin standard-pitch IC socket of PROM programmer mounted
  • Instruction manual
