| CXK5V16100TM-85LLX/10LLX 65536-word x 16-bit High Speed CMOS Static RAM For the availability of this product, please contact the sales office. Description CXK5V16100TM is a general purpose high speed CMOS static RAM organized as 65536-words by 16-bits. Operating on a single 3.3V supply, this asynchronous IC is suitable for high speed and low power consumption applications where battery back up for nonvolatility is required. Features * Extended operating temperature range: -25 to +85C * Fast access time: (Access time) -85LLX 85ns (max.) -10LLX 100ns (max.) * Low power consumption operation: Standby / DC operation 1.7W (typ.) / 3.3mW (typ.) * Single 3.3V supply: 3.3V0.3V * Fully static memory: No clock or timing strobe required * Equal access and cycle time * Common data input and output: three state output * Directly LVTTL compatible: All inputs and outputs * Low voltage data retention: 2.0V (min.) * 400mil 44pin TSOP (type II) package Block Diagram A1 A0 A7 A6 A5 A4 A3 A2 A15 A14 GND Vcc Memory Matrix 512 x 1024 Row Decoder Memory Matrix 512 x 1024 Vcc Buffer 44 pin TSOP (PIastic) Function 65536-word x 16-bit static RAM Structure Silicon gate CMOS IC GND CE UB LB OE WE Control I/O Gate Column Decoder Pre Decoder I/O Gate Column Decoder A13 A12 A11 A10 A9 A8 I/O Buffer I/O Buffer Buffer I/O1 I/O8 I/O9 I/O16 Sony reserves the right to change products and specifications without prior notice.
