Datasheets
In this chapter are the datasheets for the various devices used for the computer.
74HC00 Quadruple 2-Input NAND Gate.
W65C02S Microprocessor The pinout is the PDIP version on page 13.
SST39SF010A 1-Mbit Multi-Purpose Flash. The correct pinout is the PDIP version on page 3. This datasheet contains information for three variations of the flash chip; we are using the smallest size, so pin 1 and pin 30 are both NC.
W65C22 The pinout is all the way down on page 28.
HD44780U (LCD Display Driver) The table of commands is on pages 23-25. Table 11 on page 40 also has an interesting sequence of example commands that may be useful.
W65C51N ACIA The pinout is on page 6.
DS1813 Reset Supervisor The pinout is on page 1 and the application example is on page 2.
