DESCRIPTION
1998.6
Preliminary
65,536-Word X 16-Bit or 131,072-Word X 8-Bit STATIC RAM + 524,288-Word X 16-Bit or 1,048,576-Word X 8-Bit One Time PROM
The MS52C182A is a 65,536 -word by 16 -bit / 131,072-word by 8-bit electrically switchable 1Mb static RAM and 524,288-word by 16-bit / 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 MS52C182A 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 * 65,536-word x 16-bit / 131,072-word x 8-bit configuration SRAM and 524,288-word x 16-bit / 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 : MS52C182ATA) (Product : MS52C182ALA)
