matching compatibility
LVTTL- compatible, 3.3V (鹵150mV) power supply
for core
LVTTL compatible, selectable 3.3V (鹵150mV) or 2.5V
(鹵100mV) power supply for I/Os and control signals on
each port
Industrial temperature range (-40擄C to +85擄C) is
available at 166MHz and 133MHz
Available in a 144-pin Thin Quad Flatpack (TQFP),
208-pin fine pitch Ball Grid Array (fpBGA), and 256-pin Ball
Grid Array (BGA)
Supports JTAG features compliant with IEEE 1149.1
鈥?Due to limited pin count, JTAG is not supported on the
144-pin TQFP package.

NOTE:
1. The Bank-Switchable dual-port uses a true SRAM
core instead of the traditional dual-port SRAM core.
As a result, it has unique operating characteristics.
