| White Electronic Designs WS128K32-XG2TXE ADVANCED* 128Kx32 SRAM MULTICHIP PACKAGE, RADIATION TOLLERANT FEATURES Access Times of 35, 45, 55ns Packaging * 68 lead, 22.4mm CQFP (G2T), 4.57mm (0.180"), (Package 509) Organized as 128Kx32; User Configurable as 256Kx16 or 512Kx8 Low Power Data Retention Commercial, Industrial and Military Temperature Ranges 5V Power Supply Low Power CMOS * This product is under development, is not qualified or characterized and is subject to change or cancellation without notice. TTL Compatible Inputs and Outputs Built in Decoupling Caps and Multiple Ground Pins for Low Noise Operation Weight WS128K32-XG2TXE - 8 grams typical Radiation tolerant with epitaxial layer on die. 6T memory cells provide excellent protection against soft errors FIGURE 1 - PIN CONFIGURATION FOR WS128K32N-XG2TXE Top View NC A0 A1 A2 A3 A4 A5 CS3# GND CS4# WE1# A6 A7 A8 A9 A10 VCC Pin Description I/O0-31 A0-16 WE1-4# CS1-4# OE# VCC GND NC Data Inputs/Outputs Address Inputs Write Enables Chip Selects Output Enable Power Supply Ground Not Connected 987654 I/O0 I/O1 I/O2 I/O3 I/O4 I/O5 I/O6 I/O7 GND I/O8 I/O9 I/O10 I/O11 I/O12 I/O13 I/O14 I/O15 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 3 2 1 68 67 66 65 64 63 62 61 I/O16 I/O17 I/O18 I/O19 I/O20 I/O21 I/O22 I/O23 GND I/O24 I/O25 I/O26 I/O27 I/O28 I/O29 I/O30 I/O31 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 44 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 The White 68 lead G2T CQFP fills the same fit and function as the JEDEC 68 lead CQFJ or 68 PLCC. But the G2T has the TCE and lead inspection advantage of the CQFP form.
