17 / 68 page ![]() November 2007 Datasheet 308551-05 17 Numonyx™ Embedded Flash Memory (J3 v. D) 4.2 56-Lead TSOP Package Pinout (32/64/128 Mbit) Notes: 1. A22 exists on 64- and 128- densities. On 32-Mbit density this signal is a no-connect (NC). 2. A23 exists on 128-Mbit densities. On 32- and 64-Mbit densities this signal is a no-connect (NC) 4.3 Signal Descriptions Table 3 lists the active signals used on Numonyx™ Embedded Flash Memory (J3 v. D) and provides a description of each.

D) (Sheet 1 of 2) Symbol Type Name and Function A0 Input BYTE-SELECT ADDRESS: Selects between high and low byte when the device is in x8 mode. This address is latched during a x8 program cycle. Not used in x16 mode (i.e., the A0 input buffer is turned off when BYTE# is high). A[MAX:1] Input ADDRESS INPUTS: Inputs for addresses during read and program operations. Addresses are internally latched during a program cycle: 32-Mbit — A[21:1] 64-Mbit— A[22:1] 128-Mbit — A[23:1] 256-Mbit — A[24:1] A24 acts as a virtual CE for the two devices. A24 at VIL selects the lower die and A24 at VIH selects the upper die. D[7:0] Input/ Output LOW-BYTE DATA BUS: Inputs data during buffer writes and programming, and inputs commands during CUI writes. Outputs array, CFI, identifier, or status data in the appropriate read mode. Data is internally latched during write operations. |
