High-Speed 3.3v 32K x 18 Dual-Port Synchronous Pipelined Static RAM
Industrial and Commercial Temperature Ranges
Description:
The IDT70V3379 is a high-speed32K x 18 bit synchronous Dual-Port
RAM. The memory array utilizes Dual-Port memory cells to allow
simultaneous access of any address from both ports. Registers on control,
data, and address inputs provide minimal setup and hold times. The timing
latitude provided by this approach allows systems to be designed with very
short cycle times. With an input data register, the IDT70V3379 has been
optimized for applications having unidirectional or bidirectional data flow
in bursts. An automatic power down feature, controlled by
CE
0
and CE
1,
permits the on-chip circuitry of each port to enter a very low standby power
mode.
The 70V3379 can support an operating voltage of either 3.3V or 2.5V
on one or both ports, controllable by the OPT pins. The power supply for
the core of the device (V
DD
) remains at 3.3V.

these pins as Vss. Customers who plan to take advantage of the upgrade path should treat these pins as VSS on the 70V3379 and 70V3389. If no upgrade is
needed, the pins can be treated as NC.

NOTES:
1. V
DD
, OPT
X
, and V
DDQX
must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
2. OPT
X
selects the operating voltage levels for the I/Os and controls on that port.
If OPT
X
is set to VIH (3.3V), then that port's I/Os and controls will operate at 3.3V
levels and V
DDQX
must be supplied at 3.3V. If OPT
X
is set to VIL (0V), then that
port's I/Os and controls will operate at 2.5V levels and V
DDQX
must be supplied
at 2.5V. The OPT pins are independent of one another—both ports can operate
at 3.3V levels, both can operate at 2.5V levels, or either can operate at 3.3V
1. 内容简介 在2015年，苹果新一代的MacBook和Apple Watch皆搭载压力触控感应技术，它被Apple称为Force Touch，用户每次按下触控板之后除了可以在萤幕看见视觉回馈，它同时能够分辨出用户点按的力度强弱来做出一系列的相关操控与应用。而本文将介绍以HY16F184内建高精密Sigma-delta 24 Bit ADC搭配Uneo Force Sensor来实现一...[详细]
