HM-6514
March 1997
1024 x 4 CMOS RAM
Features
Description
• Low Power Standby . . . . . . . . . . . . . . . . . . . 125µW Max
• Low Power Operation . . . . . . . . . . . . . 35mW/MHz Max
• Data Retention . . . . . . . . . . . . . . . . . . . . . . . at 2.0V Min
The HM-6514 is a 1024 x 4 static CMOS RAM fabricated
using self-aligned silicon gate technology. The device utilizes
synchronous circuitry to achieve high performance and low
power operation.
• TTL Compatible Input/Output
• Common Data Input/Output
• Three-State Output
• Standard JEDEC Pinout
• Fast Access Time. . . . . . . . . . . . . . . . . . 120/200ns Max
• 18 Pin Package for High Density
• On-Chip Address Register
• Gated Inputs - No Pull Up or Pull Down Resistors
Required
On-chip latches are provided for addresses allowing efficient
interfacing with microprocessor systems. The data output
can be forced to a high impedance state for use in expanded
memory arrays.
Gated inputs allow lower operating current and also elimi-
nate the need for pull up or pull down resistors. The
HM-6514 is a fully static RAM and may be maintained in any
state for an indefinite period of time.
Data retention supply voltage and supply current are guaran-
teed over temperature.
