ispMACH4256ZE-TN144 CPLD
The board features the ispMACH 4000ZE CPLD which is ideal for low-power, high-volume portable applications.
The on-board ispMACH 4256ZE is the highest capacity device of the family with 256 macrocells (equivalent to
about 450 FPGA LUTs). The 144-pin TQFP package provides 96 user I/Os and 4 dedicated inputs in a 20mm x
20mm package. The ispMACH 4256ZE consumes standby current as low as 15µA. A complete description of this
device can be found in the
Table 7. ispMACH 4256ZE CPLD Interface Reference
JTAG Interface Circuits
For power and programming, a FTDI chip USB UART/FIFO IC converter provides a communication interface
between a PC host and the JTAG programming chain of the Breakout Board. The USB 5V supply is also used as a
source for the 3.3V and 1.8V supply rails. A USB mini-B socket is provided for the USB connector cable.
