M4-64

The MACH^® 4 family from Lattice offers an exceptionally flexible architecture and delivers a superior Complex Programmable Logic Device (CPLD) solution of easy-to-use silicon products and software tools. The overall benefits for users are a guaranteed and predictable CPLD solution, faster time-to-market, greater flexibility and lower cost. The MACH 4 devices offer densities ranging from 32 to 256 macrocells with 100% utilization and 100% pin-out retention. The MACH 4 family offer 5-V (M4-xxx) and 3.3-V (M4LV-xxx) operation.

MACH 4 products are 5-V or 3.3-V in-system programmable through the JTAG (IEEE Std. 1149.1) interface. JTAG boundary scan testing also allows product testability on automated test equipment for device connectivity.

All MACH 4 family members deliver First-Time-Fit and easy system integration with pin-out retention after any design change and refit. For both 3.3-V and 5-V operation, MACH 4 products can deliver guaranteed fixed timing as fast as 7.5 ns tPD and 111 MHz fCNT through the SpeedLocking feature when using up to 20 product terms per output (Table 2).

The MACH 4 family offers numerous density-I/O combinations in Thin Quad Flat Pack (TQFP), Plastic Quad Flat Pack (PQFP), Plastic Leaded Chip Carrier (PLCC), and Ball Grid Array (BGA) packages ranging from 44 to 256 pins (Table 3). It also offers I/O safety features for mixedvoltage 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 powerdown mode for extra power savings and individual output slew rate control for the highest speed transition or for the lowest noise transition.
