Functional Block Diagram
◆
Full hardware support of semaphore signaling between
ports on-chip
◆
On-chip port arbitration logic
◆
Fully asynchronous operation from either port
◆
Separate byte controls for multiplexed bus and bus
matching compatibility
◆
Sleep Mode Inputs on both ports
◆
Supports JTAG features compliant to IEEE 1149.1 in
BGA-208 and BGA-256 packages
◆
Single 2.5V (±100mV) power supply for core
◆
LVTTL-compatible, selectable 3.3V (±150mV)/2.5V (±100mV)
power supply for I/Os and control signals on each port
◆
Available in a 256-ball Ball Grid Array, 144-pin Thin Quad
Flatpack and 208-ball fine pitch Ball Grid Array
◆
Industrial temperature range (–40°C to +85°C) is available
for selected speeds
Features
◆
True Dual-Port memory cells which allow simultaneous
access of the same memory location
◆
High-speed access
– Commercial: 8/10/12/15ns (max.)
– Industrial: 10/12ns (max.)
◆
RapidWrite Mode simplifies high-speed consecutive write
cycles
◆
Dual chip enables allow for depth expansion without
external logic
◆
IDT70T633/1 easily expands data bus width to 36 bits or
more using the Master/Slave select when cascading more
than one device
◆
M/
S = VIH for BUSY output flag on Master,
M/
S = VIL for BUSY input on Slave

WITH 3.3V 0R 2.5V INTERFACE
IDT70T633/1S
1. Address A18x is a NC for IDT70T631.
2.
BUSY is an input as a Slave (M/S=VIL) and an output when it is a Master (M/S=VIH).
3
BUSY and INT are non-tri-state totem-pole outputs (push-pull).
4. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. OPTx,
INTx, M/S and the
sleep mode pins themselves (ZZx) are not affected during sleep mode.
