Applicable MCU
Operating clock frequency
Power supply
MCU socket
PCA7402B
M38B59EFFP
4 MHz
(Supplied by the ceramic oscillator mounted on the PCA7438F-80A)
Supplied from the Vcc of the PROM programmer
IC51-0804-819-6 (made by Yamaichi Electronics Co., Ltd.)
A programmable MCU mounted
(IC socket for 80-pin QFP mounted)
Interface board (buffer IC mounted)
(Connected by two rows of standard-pitch 18-pin connectors and two
rows of standard-pitch 16-pin connectors to the upper and lower
boards)
Board to be connected to the PROM programmer (for 256K bit mode)
(Standard-pitch 28-pin pin-header to be connected to the PROM
programmer mounted)
Board to be connected to the PROM programmer (for 1M bit mode)
(Standard-pitch 32-pin pin-header to be connected to the PROM
programmer mounted)

PCA7438F-80A
PCA7402D
PCA7402E
Note: The PCA7438F-80A is designed to support 38000 Series 80-pin QFP packages (80P6N-A),
and it is basically compatible with the future variations of the MCU series.
