EPM3128ATC100-10 Обзор

The Intel / Altera (formerly Altera) EPM3128ATC100-10 is a member of the MAX 3000A family of CMOS EEPROM-based Complex Programmable Logic Devices (CPLDs), delivering 128 macrocells, 80 user I/Os, and a 10 ns pin-to-pin propagation delay in a 100-pin TQFP package. It operates from a 3.3 V core supply with MultiVolt I/O that is compatible with 5.0 V, 3.3 V, and 2.5 V logic levels, enabling drop-in interfacing with mixed-voltage buses and legacy TTL parts.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip with a programmable interconnect matrix. CPLDs sit in the programmable logic hierarchy between simple PLDs (PAL/GAL) and FPGAs, offering instant-on behavior, deterministic timing, and EEPROM-based configuration that retains bitstream without external boot memory. The MAX 3000A family specifically targets glue-logic, bus-interface, and PCI-compliant bridge applications where low cost, predictable timing, and in-system programmability (ISP) outweigh the need for FPGA-class logic density.

Key features of the EPM3128ATC100-10 include in-system programmability compliant with IEEE Std. 1532 for concurrent ISP across vendors, MultiVolt I/O (5.0 V / 3.3 V / 2.5 V tolerant), PCI-SIG-compliant timing for local-bus interfacing, and a 100-pin TQFP footprint with 80 usable I/Os. The non-volatile EEPROM configuration cell eliminates the need for external configuration memory and provides instant-on operation at power-up.

Architecturally, the device uses Altera's classic MAX architecture with Logic Array Blocks (LABs), a programmable interconnect array (PIA), and per-macrocell flip-flops with selectable clear/preset and clock options. The 3.3 V core and 5 V-tolerant I/Os are fabricated on a CMOS EEPROM process that supports ISP through the JTAG (IEEE 1149.1 / IEEE 1532) interface. Counter frequencies reach 227.3 MHz, and the pin-to-pin delay of 10 ns in this speed grade suits state-machine and address-decoding tasks.

Typical applications include PCI bus interface glue logic, address decoding and chip-select generation in embedded systems, glue logic between microprocessors and peripherals, bus-width translation between 5 V MCUs and 3.3 V peripherals, and power-up sequencing logic in industrial controllers. The wide MultiVolt I/O range and PCI-compliant timing make it especially attractive for legacy industrial designs migrating between logic families.

When designing with this part, ensure that input signals conform to the I/O standard's VCCIO rail and observe the JTAG (IEEE 1149.1) tap connection requirements for ISP. Note that the EPM3128ATC100-10 is a mature, mature-lifecycle device suitable for long-life programs but typically sourced through authorized distributors due to limited active manufacturing.

This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single source for selection, replacement, and lifecycle context.

Типичное применение

EPM3128ATC100-10 подходит для 6 применениеs: PCI Bus Interface Glue Logic, Address Decoding & Chip-Select Generation, Bus-Width & Voltage Translation (5 V to 3.3 V), Glue Logic in Industrial Controllers, Power-Up Sequencing Logic, State Machine Implementation in Test Equipment.

🖥️

PCI Bus Interface Glue Logic

The EPM3128ATC100-10's PCI-SIG-compliant timing on the -10 speed grade and MultiVolt I/O make it a natural fit for PCI local-bus glue between a 3.3 V controller and 5 V peripherals. With 128 macrocells, the device can decode PCI command/address cycles, generate chip-select strobes, and arbitrate interrupts within a single chip. The 10 ns pin-to-pin delay comfortably meets the PCI 2.2 setup/hold budget at 33 MHz. Engineers typically place the CPLD between the host bridge and downstream peripherals, using the JTAG (IEEE 1532) port for in-field firmware updates.

🏭

Address Decoding & Chip-Select Generation

In embedded systems with multiple peripherals sharing a parallel bus, the EPM3128ATC100-10's 128 macrocells and 80 I/Os excel at address decoding and chip-select generation. The 10 ns tPD supports fast bus cycles without wait states on most 8/16/32-bit microcontrollers. The device's non-volatile EEPROM configuration means chip-select logic is active at power-on with no boot delay, critical in deterministic-embedded designs. Typical implementations decode 24-bit addresses into 8-16 peripheral selects, freeing the MCU from software-driven decoding.

🔧

Bus-Width & Voltage Translation (5 V to 3.3 V)

The EPM3128ATC100-10's MultiVolt I/O supports 5.0 V, 3.3 V, and 2.5 V logic levels on the same device while the core runs at 3.3 V, making it an ideal bus-width and voltage translator between legacy 5 V microcontrollers and modern 3.3 V peripherals. With 80 user I/Os the device can bridge full 32-bit data buses plus control signals without external logic. The 10 ns delay is fast enough for parallel bus operation in the low-MHz range commonly used in industrial control boards.

🏭

Glue Logic in Industrial Controllers

Industrial controllers often require deterministic, instant-on glue logic for sensor multiplexing, encoder decoding, motor-control timing, and power-sequencing tasks. The EPM3128ATC100-10's non-volatile EEPROM, 0-70 C commercial operating range, and 10 ns deterministic delay suit these long-life industrial programs. The 100-pin TQFP package is hand-solderable for low-volume production and reflow-friendly for high-volume assembly. Engineers use the JTAG port for in-field ISP when firmware revisions are needed after deployment.

⚡

Power-Up Sequencing Logic

Multi-rail systems (FPGA + DDR + analog + MCU) require deterministic power-up sequencing to prevent latch-up and bus contention. The EPM3128ATC100-10's instant-on EEPROM behavior - active at the first clock edge - provides a simple, robust sequencer without boot ROM. With 128 macrocells the device can generate enable strobes for 4-8 power rails with adjustable delay chains implemented in logic. The MultiVolt I/O allows the sequencer to operate at 5 V while monitoring 3.3 V power-good signals.

🔧

State Machine Implementation in Test Equipment

Bench-top and production test equipment relies on deterministic state machines for handshake protocols, fixture control, and measurement sequencing. The EPM3128ATC100-10 delivers predictable 10 ns state transitions across 128 macrocells, allowing complex multi-state sequencers (UART bridges, SPI/I2C controllers, parallel-test pattern generators) in a single chip. Counter frequencies up to 227.3 MHz support high-speed timing generation. The TQFP-100 footprint is breadboard-friendly with breakout adapters for prototyping.

The part is widely used for glue logic and PCI bus-interface applications.
What is the difference between EPM3128ATC100-10 and EPM3128ATC100-7?
Both parts share the same MAX 3000A architecture, 128 macrocells, 80 I/Os, and 100-pin TQFP package; they differ only in speed grade. The EPM3128ATC100-10 has a 10 ns pin-to-pin delay (slower, lower cost), while the EPM3128ATC100-7 offers a 7.5 ns delay. They are drop-in compatible at the PCB level - swapping them requires no layout change, only timing re-validation.
How many user I/Os does the EPM3128ATC100-10 have?
The EPM3128ATC100-10 provides 80 user I/O pins according to the Altera MAX 3000A datasheet. The 100-pin TQFP package dedicates the remaining 20 pins to power, ground, JTAG, and dedicated configuration inputs, leaving 80 pins available for general-purpose user I/O across four I/O banks.
Is the EPM3128ATC100-10 5V tolerant?
Yes. The EPM3128ATC100-10 supports Altera's MultiVolt I/O interface, allowing its I/O pins to operate with 5.0 V, 3.3 V, or 2.5 V logic levels while the core runs at 3.3 V. According to the Altera datasheet, this makes the device compatible with mixed-voltage buses and legacy 5 V peripherals without external level shifters.

What is the best Xilinx equivalent for EPM3128ATC100-10?
There is no pin-compatible Xilinx drop-in for the EPM3128ATC100-10 because the 100-pin TQFP footprint, JTAG pinout, and macrocell-based architecture are Altera-proprietary. For Xilinx-based designs targeting the same CPLD role, evaluate the Xilinx XC9500XL family (e.g., XC9536XL/XC9572XL) but expect a PCB redesign. For a true drop-in on the same 100-pin TQFP, stay within the Altera MAX 3000A family (EPM3064 / EPM3128 variants).

Руководство по выбору

Choose the EPM3128ATC100-10 when you need 128 macrocells of MAX 3000A CPLD logic with a 10 ns pin-to-pin delay, 80 user I/Os, and MultiVolt I/O for mixed-voltage systems. Choose the EPM3128ATC100-7 if your design has tighter timing budgets (7.5 ns vs 10 ns) - same footprint, same architecture, just faster. Choose the EPM3128ATC100-10N if you need RoHS / lead-free compliance for EU or automotive markets. Choose the EPM3064ATC100-10 if 64 macrocells suffice and cost is the primary driver - same TQFP-100 package, half the logic density. All four parts share the same MAX 3000A architecture, JTAG (IEEE 1532) ISP, and MultiVolt I/O, enabling straightforward migration within the family. Avoid using the -10 grade in designs that require explicit PCI compliance if your bus frequency approaches 33 MHz - validate against the -7 or -4 grades.

Заметки по проектированию

The EPM3128ATC100-10 requires a clean 3.3 V VCCINT rail with at least 100 mA of current headroom for I/O switching transients. Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and add a bulk 10 uF tantalum or ceramic capacitor near the package. Each VCCIO bank (1-4) must be tied to the appropriate I/O logic-level supply (5.0 V, 3.3 V, or 2.5 V) and individually bypassed with 0.1 uF capacitors. VCCIO banks may be powered independently, allowing mixed-voltage designs on a single chip.

Route the JTAG signals (TDI, TDO, TMS, TCK) with short, parallel traces and a 10 kohm pull-up on TCK and TMS to prevent spurious boundary-scan activity. Maintain a continuous ground plane under the TQFP-100 package; do not route signal traces beneath the device body. Keep high-speed I/O traces short (< 5 cm) and series-terminate when driving capacitive loads > 25 pF. The exposed thermal pad (if present on TQFP-100) should be soldered to a copper pour to reduce thermal resistance.

Three common pitfalls: (1) Do not leave VCCIO banks floating - unused banks still require their VCCIO pin tied to a valid supply (typically 3.3 V) for the I/O buffers to behave predictably. (2) Do not exceed the 5.0 V I/O absolute-maximum rating even momentarily during hot-plug events; use external clamping if the device may be hot-swapped. (3) Do not assume any speed grade supports all PCI timing - only the -4 to -10 grades are PCI-compliant per the MAX 3000A datasheet; verify PCI bus-timing budgets against the specific speed grade used.

RoHS / lead-free compliance could not be verified from the verified web data; the -10N variant suffix typically indicates lead-free / RoHS-compliant packaging per Altera naming convention, but this should be confirmed against the manufacturer certificate of compliance (CoC) before use in EU or automotive markets. The part is not AEC-Q100 qualified and is rated for commercial 0 C to 70 C operation only.
