Semiconductor MS52C181A
131,072-Word X 8-Bit STATIC RAM + 1,048,576-Word X 8-Bit One Time PROM
DESCRIPTION
1998.6
Preliminary
The MS52C181A is a131,072-word by 8-bit electrically switchable 1Mb static RAM and 1,048,576-word by 8-bit electrically switchable 8Mb One Time PROM featuring 2.7V to 3.6V power supply operation and direct LVTTL input / output compatibility. Since the circuitry is completely static,external clocks are unnecessary,making this device very easy to use. The MS52C181A is packaged in 44-pin plastic TSOP and 48-pin FBGA (9mmx10mm) ,suited for use in handy terminal and other application which required small space.
FEATURES * 131,072-word x 8-bit configuration SRAM and 1,048,576-word x 8-bit configuration OTP * Power supply voltage : 2.7 to 3.6V * Fully static operation * Operating temperature range : Ta= -20 to 70C * Access time : 100nS MAX (Vcc=2.7V) 80nS MAX (Vcc=3.0V) * Common address inputs and data inputs / outputs for SRAM and OTP * Input / Output LVTTL compatible * 3-state output * Data retention available at power supply voltage 1.5V for SRAM * Package options : 44-pin plastic TSOP (Type II) 48-pin plastic FBGA (TSOP44-P-400-0.8) (FBGA48-P-0910-0.8) (Product : MS52C181ATA) (Product : MS52C181ALA)
