S1C6P466 TECHNICAL MANUAL EPSON 99
CHAPTER 5: PROM PROGRAMMING AND OPERATING MODE
The serial programming is performed using the 1 MHz clock supplied from the PROM writer to the
CLKIN terminal. Take noise measure into consideration so that noise does not affect the clock line input
to the CLKIN terminal when designing the target board.
5.2.3 Parallel programming mode
The parallel programming can be performed by installing the S1C6P466 to the exclusive PROM writer via
the adaptor socket. In this mode, it is not necessary to set up the programming terminals since it is
controlled by the exclusive PROM writer. For the S1C6P466, the adaptor socket for the QFP17-144pin
package only is available. Note that the QFP8-144pin package is not supported.
