64K x 72 SRAM Module 128K x 72 SRAM Module 256K x 72 SRAM Module 512K x 72 SRAM Module
Features
* Operates at 66 MHz * Uses 64K x 18, 128K x 18, or 256K x 18 high performance synchronous SRAMs * 168-position Angled DIMM from Amp p/n 179508-2 * 3.3V inputs/data outputs surface mount packages on an epoxy laminate board with pins. The modules are designed to be incorporated into large memory arrays. The module is configured as either one or two banks, where each bank has separate chip select and output enable controls. Separate clocks are provided for every pair of SRAMs's. Multiple ground pins and on-board decoupling capacitors ensure high performance with maximum noise immunity. All components on the cache modules are surface mounted on a multi-layer epoxy laminate (FR-4) substrate. The contact pins are plated with 150 micro-inches of nickel covered by 30 micro-inches of gold flash.
Functional Description
The CYM9260, CYM9261, CYM9262, and the CYM9263 are high-performance synchronous memory modules organized as 64K(9260), 128K(9261), 256K(9262), or 512K(9263) by 72 bits. These modules are constructed from either 128K x 18(9260,9261B,9262A) or 256K x 18 (9263) SRAMs in plastic

Notes: 2. Resistor values for VCCQ=3.3V are R1= 317 and R2= 351 . 3. Unless otherwise noted, test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified I OL/IOH and load capacitance. Shown in (a) and (b) of AC test loads. All measurements are made at room temperature. 4. tEOZ is specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured 500 mV from steady-state voltage.
