General Description
CYM9270 General Description
The CYM9270, CYM9271B, CYM9272A, and the CYM9273 are high-performance synchronous memory modules organized as 64K(9270), 128K(9271B), 256K(9272A), 512K(9273) by 36 bits. These modules are constructed using either 128K x 18 SRAMs (9270, 9271B, 9272A) or 256K x 18 SRAMs (9273) in plastic surface mount packages on an epoxy laminate board with pins. The modules are designed to be incorporated into large memory arrays.
The modules are configured as single banks or multiple banks depending on the SRAM used to make the module. Separate clock are provided for each of the banks. Separate clocks are provided for each of the SRAMs.
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.
