CXK77S36L80AGB / CXK77S18L80AGB 4/42/43/44

8Mb Late Write HSTL High Speed Synchronous SRAMs (256K x 36 or 512K x 18 Organization)

Preliminary

Description

The CXK77S36L80AGB (organized as 262,144 words by 36 bits) and the CXK77S18L80AGB (organized as 524,288 words

by 18 bits) are high speed CMOS synchronous static RAMs with common I/O pins. These synchronous SRAMs integrate input

registers, high speed RAM, output latches, and a one-deep write buffer onto a single monolithic IC. Register - Latch (R-L) read

operations and Late Write (LW) write operations are supported, providing a high-performance user interface.

All address and control input signals except G (Output Enable) and ZZ (Sleep Mode) are registered on the rising edge of K

(Input Clock).

During read operations, output data is driven valid from the falling edge of K, one half clock cycle after the address is registered.

During write operations, input data is registered on the rising edge of K, one full clock cycle after the address is registered. Write

operations are internally self-timed, eliminating the need for complex off-chip write pulse generation.

The output drivers are series terminated, and the output impedance is programmable through an external impedance matching

resistor RQ. By connecting RQ between ZQ and V_SS, the output impedance of all DQ pins can be precisely controlled.

Sleep (power down) mode control is provided through the asynchronous ZZ input. 250 MHz operation is obtained from a single

3.3V power supply. JTAG boundary scan interface is provided using a subset of IEEE standard 1149.1 protocol.
