EMP216MGAF Series
2Mx16 Pseudo Static RAM
2Mb x16 Pseudo Static RAM Specification
GENERAL DESCRIPTION
The EMP216MGAF series is 33,554,432 bits of Pseudo SRAM which uses DRAM type memory cells, but
this device has refresh-free operation and extreme low power consumption technology. Furthermore the
interface is compatible to a low power Asynchronous type SRAM. The EMP216MGAF is organized as
2,097,152 Words x 16 bit.
FEATURES
- Organization :2M x16
- Power Supply Voltage : 2.7 ~ 3.3V
- Separated I/O power(VccQ) & Core power(Vcc)
- Three state outputs
- Byte read/write control by UB# / LB#
- Support Page Read/Write operation with 16 words
- Support Direct Deep Power Down control by ZZ# and Auto-TCSR for power saving
- Package type : 48-FPBGA 6.0x8.0

Stresses greater than those listed above “Absolute Maximum Ratings” may cause permanent damage to the device. Functional
operation should be restricted to recommended operating condition. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
2. Undershoot at power-off : -1.0V in case of pulse width < 20ns
