Description
The IDT70121/IDT70125 are high-speed 2K x 9 Dual-Port Static
RAMs. The IDT70121 is designed to be used as a stand-alone 9-bit Dual-
Port RAMor as a “MASTER” Dual-Port RAMtogether with the IDT70125
“SLAVE” Dual-Port in 18-bit-or-more word width systems. Using the IDT
MASTER/SLAVE Dual-Port RAMapproach in 18-bit-or-wider memory
systemapplications results in full-speed, error-free operation without the
need for additional discrete logic.
Both devices provide two independent ports with separate control,
address, and I/O pins that permt independent, asynchronous access for
reads or writes to any location in memory. An automatic power-down
feature, controlled by
CE
, permts the on-chip circuitry of each port to enter
a very low standby power mode.
The IDT70121/IDT70125 utilizes a 9-bit wide data path to allow for
Data/Control and parity bits at the users option. This feature is especially
useful in data communications applications where it is necessary to use a
parity bit for transmssion/reception error checking.
Fabricated using IDT’s CMOS high-performance technology, these
devices typically operate on only 675mW of power. Low-power (L)
versions offer battery backup data retention capability with each port
typically consumng 200μW froma 2V battery.
The IDT70121/IDT70125 devices are packaged in a 52-pin PLCC.
NOTES:
1. All V
CC
pins must be connected to power supply.
2. All GND pins must be connected to ground supply.
3. Package body is approximately .75 in x .75 in x .17 in.
4. This package code is used to reference the package diagram
5. This text does not indicate orientation of the actual part-marking.
