EPM3128ATC144-5N - MAX 3000A 128-Macro 5ns CPLD | Altera
MPN: EPM3128ATC144-5N ⚠ Lần mua cuốiEPM3128ATC144-5N Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL spld devices and high-density FPGAs in the programmable logic hierarchy. CPLDs use a classic AND/OR PLA architecture with non-volatile EEPROM configuration memory, providing instant-on behavior at power-up, deterministic timing, and high pin-to-pin performance - features that make them well suited for glue logic, bus interfacing, and control-plane applications. The MAX 3000A family is positioned for cost-sensitive, high-volume designs where FPGAs would be overkill but discrete logic is too inflexible.
Key specifications include 96 user I/O pins, 3.3 V core voltage, in-system programmability (ISP) via JTAG, 4.5 ns pin-to-pin delay, and commercial 0C to 70C operating temperature range. The device features MultiVolt I/O pins that can interface with 5.0 V, 3.3 V, and 2.5 V logic, plus 3.3-V ISP through the JTAG interface. Built-in JTAG boundary-scan (IEEE Std 1149.1) simplifies board-level test and programming.
The MAX 3000A architecture combines a global interconnect fabric with multiple logic array blocks (LABs), each containing 16 macro cells. Each macro cell provides a programmable register with clock enable, clear, and preset logic, allowing flexible implementation of state machines, decoders, and arithmetic functions. The deterministic interconnect guarantees fixed, predictable propagation delays independent of design placement.
Typical applications include address decoding for processor and memory buses, peripheral glue logic, bus arbitration, I/O expansion, and power-up sequencing controllers. The MAX 3000A family is also widely used in industrial control, telecommunications equipment, and consumer electronics where deterministic timing and instant-on non-volatile configuration are required.
When designing with the EPM3128ATC144-5N, use Altera's Quartus II design software (or MAX+PLUS II for legacy designs) for synthesis, fitting, and programming file generation. The 144-pin TQFP package is pin-compatible with other MAX 3000A and MAX 7000 family devices in the same package, simplifying migration paths. Programming via JTAG is recommended for production; the 3.3-V ISP eliminates the need for a separate programmer.

Ứng dụng tiêu biểu
EPM3128ATC144-5N phù hợp cho 6 Áp dụngs: Processor Address Bus Decoding, Industrial Control Glue Logic, Bus Arbitration and Interface Bridging, Power-Up Sequencing and Reset Controllers, Peripheral I/O Expansion and Multiplexing, Telecom Line Card Interface Logic.
Processor Address Bus Decoding
The EPM3128ATC144-5N is widely used as an address decoder between a microprocessor/microcontroller and memory or peripheral devices. Its 5 ns pin-to-pin delay ensures the chip-select signals are valid well before the processor's memory access timing window closes, eliminating wait states on fast buses. The 128 macro cells comfortably handle complex memory maps with chip-enable, output-enable, and write-enable logic for multiple banks, while 96 user I/Os provide ample connections for 24-32 bit address buses plus control signals. The non-volatile EEPROM configuration means the decoder comes up active at power-on with no boot delay.
Được đề xuất
Industrial Control Glue Logic
In industrial automation and motor control systems, the EPM3128ATC144-5N consolidates discrete 74-series logic (decoders, multiplexers, flip-flops, state machines) into a single programmable device. The 96 user I/Os interface directly to 5.0 V sensors, 3.3 V logic, and 2.5 V DSP/MCU signals via MultiVolt I/O. Industrial glue-logic functions such as safety interlocks, PWM blanking, fault latching, and communication-protocol bit-banging fit comfortably in 128 macro cells. The deterministic 5 ns timing is critical for safety functions where unpredictable FPGA place-and-route delays would be unacceptable.
Được đề xuất
Bus Arbitration and Interface Bridging
The EPM3128ATC144-5N bridges asynchronous bus protocols (e.g. ISA-to-PCI bridges, memory-to-peripheral, or parallel-to-multiplexed conversions) with deterministic timing guarantees. Its 96 user I/Os and 128 macro cells are well-suited for multi-master arbitration logic, dual-ported memory interfaces, and protocol-conversion state machines. The instant-on non-volatile configuration eliminates the configuration-latency issue that FPGAs exhibit, which is critical when the CPLD must arbitrate bus access at reset. JTAG in-system programmability allows field firmware updates without removing the part.
Được đề xuất
Power-Up Sequencing and Reset Controllers
The EPM3128ATC144-5N serves as a multi-rail power supply sequencer in networking equipment, servers, and telecom hardware where multiple voltage rails must come up in a specific order with precise delays. The 128 macro cells provide enough logic to implement cascade turn-on chains for 6-8 rails with adjustable delays, fault monitoring, and watchdog functions. Critically, the non-volatile EEPROM-based configuration means the sequencer is active at t=0 of power-up, before any MCU or FPGA can boot - a function that volatile-configuration FPGAs cannot perform without external supervision.
Được đề xuất
Peripheral I/O Expansion and Multiplexing
When an MCU or ASIC runs short of GPIO pins, the EPM3128ATC144-5N provides up to 96 additional I/Os multiplexed or expanded from a smaller host pin count. The device can implement I2C-to-parallel port expanders, SPI-to-GPIO bridges, keyboard scan matrices, or 7-segment display drivers. MultiVolt I/O lets the CPLD talk directly to 5 V peripherals while interfacing with a 3.3 V or 2.5 V host MCU on the same chip - eliminating discrete level shifters. The 227.3 MHz internal counter supports high-speed SPI clock generation.
Được đề xuất
Telecom Line Card Interface Logic
In telecom line cards and access equipment, the EPM3128ATC144-5N implements E1/T1 framers, HDLC controllers, time-slot interchangers, and alarm-monitoring logic with deterministic timing. The 96 I/Os connect directly to TDM buses, status LEDs, and backplane signals via 5 V / 3.3 V MultiVolt I/O. 128 macro cells handle framing, error-checking, and interrupt aggregation for multiple channels. Commercial 0-70C temperature grade suits temperature-controlled central-office environments, while in-system programmability allows line-card firmware updates via JTAG.

Ghi chú thiết kế
Estimated: The EPM3128ATC144-5N draws approximately 80-150 mA from VCCINT (3.3 V core) and additional current from VCCIO banks, depending on I/O toggle rate and output loading. Provide at least four 0.1 uF decoupling capacitors placed within 5 mm of each VCC pin group (typically one per package corner), plus a single 10 uF bulk capacitor near the supply entry. MultiVolt I/O banks (VCCIO) may each be tied to 5.0 V, 3.3 V, or 2.5 V independently - but all VCCINT pins must share a common 3.3 V rail with low-impedance ground return.
The 144-pin TQFP package has 0.5 mm pitch leads - PCB layout must use solder-mask-defined (SMD) pads with 0.275 mm pad width and 0.20 mm solder-mask opening to prevent solder bridging. Place all four JTAG signals (TCK, TMS, TDI, TDO) on a dedicated test header or boundary-scan chain accessible from the board edge. Keep the JTAG trace lengths under 100 mm to avoid signal-integrity issues at high TCK frequencies; add 10 kohm pull-ups on TMS and TDI per IEEE 1149.1 recommendations.
Estimated: Three common pitfalls when migrating from EPM3128ATC144-5 to EPM3128ATC144-5N: (1) the 'N' suffix indicates lead-free / RoHS-compliant reflow profile - peak temperature must reach 245-250C, not the 215C of leaded parts; (2) the -5 speed grade is the fastest available - confirm Quartus fitter selects the correct device speed, as the -7 and -10 variants use identical JEDEC STAPL files but produce slower fMAX; (3) MAX 3000A devices do not have built-in pull-ups on I/O pins - external 10 kohm resistors are required for inputs that may float during power-up, otherwise inrush current can exceed 50 mA.
MultiVolt I/O outputs drive 5.0 V TTL levels when VCCIO is tied to 5 V - but the output edge rate of approximately 2-3 ns can generate significant ground bounce on parallel-bus interfaces. Place series damping resistors (22-33 ohm) on heavily-loaded address/data buses, or use the slower slew-rate I/O option in Quartus to reduce EMI. For clock outputs, route on the inner PCB layer with continuous ground plane reference and keep trace length matching within 2 mm across all clock nets.
Estimated: When migrating between TQFP-144 and TQFP-100 variants of MAX 3000A, only the inner-package pins differ in function - I/O pin assignments are NOT directly compatible. A 144-pin to 100-pin footprint adapter is required and will typically restrict usable I/Os to ~80. For new designs that may need migration, allocate pin assignments to the inner 80 I/O positions first so the design can be re-targeted to a TQFP-100 package with minimal rework.
