Pin Assignments
4 Vss_ic, 4 Vcc_i, 4 Vss_o, 2 Vcc_o, 2Vcc_c
NOTE: The Vss-ic and Vcc_i are for input and noise sensitive circuits. Sclk signals in the range of 3 to 6 ns and within TTL input levels may
alter expected read or write functions. The Vss _o and Vcc _o pins are used for the high current drivers. De-coupling capacitors should be used
as close to the device power pins as possible. Address bit A6 is not used. See “Host Interface” section.
