Busy and Interrupt Flags
On-chip port arbitration logic
Full on-chip hardware support of semaphore signaling
between ports
Devices are capable of withstanding greater than 2001V
electrostatic discharge.
Fully asynchronous operation from either port
Battery backup operation—2V data retention
TTL-compatible, single 5V (
±
10%) power supply
Available in 84-pin PGA, 84-pin quad flatpack, 84-pin
PLCC, and 100-pin Thin Quad Plastic Flatpack
Industrial temperature range (–40
°
C to +85
°
C) is avail-
able, tested to military electrical specifications
FUNCTIONAL BLOCK DIAGRAM
FEATURES:
True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
High-speed access
— Military: 20/25/35/55/70ns (max.)
— Commercial: 15/17/20/25/35/55ns (max.)
Low-power operation
— IDT7024S
Active: 750mW (typ.)
Standby: 5mW (typ.)
— IDT7024L
Active: 750mW (typ.)
Standby: 1mW (typ.)
Separate upper-byte and lower-byte control for
multiplexed bus compatibility
IDT7024 easily expands data bus width to 32 bits or
more using the Master/Slave select when cascading
NOTES:
1. (MASTER):
BUSY
is output;
(SLAVE):
BUSY
is input.
2.
BUSY
outputs
and
INT
outputs
are non-tri-stated
push-pull.
