EPM3128ATC144-7N Ringkasan

The Altera (now Intel) EPM3128ATC144-7N is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, providing 128 macrocells, 96 user I/Os, and a 7.5 ns pin-to-pin propagation delay in a 144-pin TQFP (Plastic Thin Quad Flat Pack) package with a 3.3 V core supply. The device delivers up to 10,000 usable gates, supports counter frequencies up to 227.3 MHz, and includes MultiVolt I/O interfaces compatible with 5.0 V, 3.3 V, and 2.5 V logic levels. Speed grades -4 through -10 are compatible with the PCI Local Bus Specification, Revision 2.2 (PCI SIG).

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks on a single chip with a programmable interconnect matrix. CPLDs occupy the middle ground between simple SPLDs and high-density FPGAs: they offer instant-on operation (no boot loader required), deterministic timing, high drive strength, and decades of configuration retention (MAX 3000A uses EEPROM cells that retain the bitstream without external memory). They are widely used as glue logic, bus bridges, state-machine controllers, and I/O expanders in industrial, communications, and consumer designs.

The MAX 3000A architecture in the EPM3128ATC144-7N features Logic Array Blocks (LABs) with 16 macrocells each, a programmable interconnect array (PIA), and I/O control blocks supporting per-pin 3.3 V PCI-compliant drive. In-system programmability (ISP) is supported via the 3.3 V JTAG interface (IEEE Std. 1149.1), enabling field updates and production-line programming. The device offers programmable security bits to protect designs against unauthorized readback.

Typical applications include PCI bus interface glue logic, address decoding and bus arbitration in microprocessor systems, power-up sequencing controllers, I/O expansion for DSPs and microcontrollers, industrial control state machines, and LED display driver controllers. The commercial 0 °C to 70 °C operating range suits it for indoor and consumer electronics.

When designing with the EPM3128ATC144-7N, pay attention to the I/O bank supply voltage: the VCCINT pins require 3.3 V while the VCCIO pins can be driven at 2.5 V, 3.3 V, or 5.0 V for mixed-voltage interfacing. The TQFP-144 package requires a 1.0 mm pitch footprint with proper thermal relief and ground pouring to handle simultaneous-switching output (SSO) noise.
