The ispMACH 4A family offers 20 density-I/O combinations in Thin Quad Flat Pack (TQFP),
Plastic Quad Flat Pack (PQFP), Plastic Leaded Chip Carrier (PLCC), Ball Grid Array (BGA), fine-
pitch BGA (fpBGA), and chip-array BGA (caBGA) packages ranging from 44 to 388 pins (Table
3). It also offers I/O safety features for mixed-voltage designs so that the 3.3-V devices can accept
5-V inputs, and 5-V devices do not overdrive 3.3-V inputs. Additional features include Bus-
Friendly inputs and I/Os, a programmable power-down mode for extra power savings and
individual output slew rate control for the highest speed transition or for the lowest noise
transition.
