EPM3064ATC100-10NA Visão geral

The Intel (formerly Altera) EPM3064ATC100-10NA is a member of the MAX 3000A family of Complex Programmable Logic Devices (CPLDs), delivering 64 macrocells, 66 user I/Os, and a 10 ns pin-to-pin propagation delay in a 100-pin TQFP package. It is a non-volatile, in-system programmable logic device targeted at glue-logic, interface bridging, and bus decoding applications where deterministic timing and instant-on behavior are required. The 'A' suffix denotes the second-generation MAX 3000A architecture with 3.3V core operation, while the '10' speed grade corresponds to a 10 ns tPD.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix. In the broader programmable logic taxonomy, CPLDs sit below FPGAs in density but offer deterministic timing, instant-on from non-volatile storage, and are well-suited for high-speed control logic, address decoding, state-machine implementation, and bus-interface bridging. The MAX 3000A family belongs to the 'low-cost, 3.3V CPLD' tier of Altera's (now Intel PSG) CPLD portfolio and is a derivative of the original MAX 7000 architecture with 3.3V core rails and IEEE 1532 in-system programmability.

Key features include 1,250 usable gates, four dedicated input pins with global clock distribution, JTAG (IEEE 1149.1) boundary-scan test support, IEEE 1532-compliant in-system programmability, and MultiVolt I/O supporting 2.5V/3.3V/5.0V mixed-voltage interfacing. The non-volatile EEPROM configuration cells guarantee instant-on operation with no external boot memory. The 100-pin TQFP package is a thin plastic quad flat pack with 0.5 mm lead pitch, suitable for surface-mount assembly in industrial temperature grades (-40C to +85C for the commercial 'C' variant; the 'NA' suffix here denotes the lead-free, industrial-grade order code).

The EPM3064ATC100-10NA architecture consists of four Logic Array Blocks (LABs) interconnected by a continuous programmable interconnect array (PIA). Each LAB contains 16 macrocells built around a product-term array, a programmable register, and configurable I/O control. The IEEE 1149.1 JTAG interface provides boundary-scan test capability and supports in-system programming concurrent with normal device operation. Built-in BST (Boundary-Scan Test) circuitry simplifies board-level interconnect testing without external test fixtures.

Typical applications include bus decoding and address latching in microcontroller or microprocessor systems, glue-logic replacement for discrete 74-series TTL/CMOS parts, I/O expansion and signal-level translation between 5V and 3.3V domains, state-machine and sequencer implementation for industrial control boards, and power-up/down sequencing logic in multi-rail systems. The instant-on non-volatile configuration is especially valued in safety-critical or deterministic-latency applications where FPGA boot delays are unacceptable.

When designing with this device, ensure that the Quartus II (or MAX+PLUS II) toolchain is used for synthesis, fitting, and programming file generation. Decoupling capacitors (0.1 uF ceramic per VCC pin plus bulk) should be placed close to the supply pins. Unused I/O pins should be configured as outputs driving known logic levels to minimize power consumption and switching noise.

Aplicações típicas

EPM3064ATC100-10NA é adequado para 6 aplicaçãos: Microprocessor Bus Address Decoding, Glue-Logic Replacement (74-series Substitution), Mixed-Voltage I/O Bridging (5V <-> 3.3V Translation), Industrial Control State Machines, Power-Up / Power-Down Sequencing Controllers, JTAG/Boundary-Scan Test Infrastructure.

🔧

Microprocessor Bus Address Decoding

The EPM3064ATC100-10NA fits microprocessor bus address-decoding applications because it provides 64 macrocells with a deterministic 10 ns pin-to-pin propagation delay and instant-on non-volatile configuration. In a typical 8/16/32-bit microcontroller or DSP system, the CPLD is placed between the processor address bus and peripheral chip-select pins, replacing discrete 74HC138/139/154 decoder logic. The 64 macrocells handle 8-16 chip-select outputs with multiple enable equations, while the 10 ns tPD guarantees a clean chip-select setup window even at high memory-bus frequencies. The non-volatile EEPROM cells mean decoding logic is active at power-on with no FPGA boot latency, critical for boot ROM selection and watchdog reset sequencing.

Glue-Logic Replacement (74-series Substitution)

The EPM3064ATC100-10NA is widely used to replace multiple discrete 74HC/74AHC/74LVTH series TTL glue-logic gates (AND, OR, XOR, flip-flops, counters, multiplexers) on legacy and new motherboard designs. A single 64-macrocell CPLD in TQFP-100 absorbs 5-15 discrete SSI/MSI packages, reducing PCB area, BOM count, and assembly cost. The 10 ns tPD meets the timing requirements of legacy 33-66 MHz PCI and ISA bus interfaces, while MultiVolt I/O supports mixed 5V/3.3V/2.5V domain bridging. Designers benefit from instant design changes via JTAG re-programming during prototype iteration, eliminating board respins for logic corrections.

Mixed-Voltage I/O Bridging (5V <-> 3.3V Translation)

The EPM3064ATC100-10NA's MultiVolt I/O architecture makes it well suited for voltage-level translation between 5.0V legacy peripherals and 3.3V modern ASICs/FPGAs. Each I/O bank can be independently powered at 2.5V, 3.3V, or 5.0V, allowing one CPLD to bridge an 8-bit or 16-bit bus across voltage domains without external level-shifters. The 100-pin TQFP package provides 66 user I/Os - more than enough for a 32-bit bidirectional bridge with control signals. The 10 ns tPD introduces only a small latency penalty for level translation, negligible for peripheral buses like SPI, I2C, UART, and parallel ports.

Industrial Control State Machines

Industrial control and factory-automation boards use the EPM3064ATC100-10NA to implement deterministic state machines for sequencer logic, motor-step control, conveyor indexing, and safety interlocks. The deterministic 10 ns tPD with worst-case timing closure (no FPGA routing variability) makes the CPLD ideal for hard-real-time control loops where logic latency must be guaranteed cycle-by-cycle. With 64 macrocells, designers can implement 4-8 concurrent FSMs (each typically 4-16 states) with combinational flag decoding. The non-volatile instant-on behavior is critical for safety circuits that must assert correct states at power-up, even before firmware boot.

Power-Up / Power-Down Sequencing Controllers

Multi-rail systems (ATX motherboards, telecom cards, FPGA-based SoCs) require precise power-rail sequencing to prevent latch-up, in-rush current, and bus contention. The EPM3064ATC100-10NA implements these sequencers using a handful of macrocells per rail, asserting PG (power-good) and EN signals in a programmed order with adjustable delays. The non-volatile configuration is active the instant 3.3V core rail is stable - no boot PROM, no FPGA bitstream delay. With 66 user I/Os, a single CPLD sequences 6-10 rails plus monitors fault signals, replacing a chain of discrete timers and supervisors.

JTAG/Boundary-Scan Test Infrastructure

The EPM3064ATC100-10NA includes built-in IEEE Std. 1149.1 JTAG and IEEE Std. 1532 ISP interfaces, making it both a logic device and a board-level boundary-scan controller. In complex multi-IC boards, the CPLD can be programmed to chain TAP signals, multiplex JTAG paths between multiple JTAG devices, and implement custom BSDL test access logic. With 64 macrocells and 66 I/Os, it provides sufficient logic to drive TAP chains across FPGAs, ASICs, and DSPs while supporting INTEST, EXTEST, and SAMPLE/PRELOAD instructions. The non-volatile instant-on ensures JTAG infrastructure is available before any other device's firmware has booted, simplifying bring-up and field diagnostics.

What is the EPM3064ATC100-10NA?
The EPM3064ATC100-10NA is an Intel (formerly Altera) MAX 3000A family CPLD with 64 macrocells, 66 user I/Os, and a 10 ns pin-to-pin propagation delay, housed in a 100-pin TQFP package. According to the Altera MAX 3000A datasheet family document, this device is targeted at low-cost, 3.3V, instant-on logic integration where deterministic timing and non-volatile configuration are required. The 'NA' suffix denotes the lead-free, industrial-grade order code.
What is the difference between EPM3064ATC100-10NA and EPM3064ATC100-10N?
The EPM3064ATC100-10NA is the lead-free, RoHS-compliant ordering code variant of the EPM3064ATC100-10N. Both share the same MAX 3000A silicon die, the same TQFP-100 package footprint, the same 10 ns tPD speed grade, and the same 64-macrocell / 66-I/O logic capacity. The 'NA' vs 'N' difference is a packaging/lead-finish ordering code distinction for compliance with RoHS directives; electrical parameters are identical per the MAX 3000A datasheet.
Where can I buy EPM3064ATC100-10NA online?
As of 2026-09-12, the EPM3064ATC100-10NA is stocked at Heisener (4,944 pieces listed in inventory) and is also available on quote/lead-time from DigiKey, Mouser, LCSC, Win Source, Veswin, and Nantian per the verified distributor listings.

As of 2026-09-12, Heisener shows in stock with shipment Jul 7 - Jul 12 for expedited orders. Authorized franchised distributor stock (DigiKey/Mouser) for this exact order code is typically quote-based with lead time confirmed at order entry. For low-risk sourcing, request a current quote from a franchised distributor; for prototype volumes, Heisener and LCSC provide faster off-the-shelf availability.
Is EPM3064ATC100-10NA in stock?
Yes, as of 2026-09-12 the EPM3064ATC100-10NA is in stock at Heisener with 4,944 units listed in inventory. DigiKey and Mouser list the part with 'to be confirmed' lead time per the verified distributor data. For high-volume production orders, contact Intel PSG or an authorized franchised distributor for allocation.
What is the maximum operating frequency of EPM3064ATC100-10NA?
The MAX 3000A family datasheet specifies the EPM3064ATC100-10NA at a 10 ns pin-to-pin propagation delay (tPD). The corresponding maximum toggle frequency (fMAX) is in the range of 100-150 MHz depending on internal/external timing parameters; the exact fMAX number for this specific speed grade was not present in the verified web snippets and is marked as [DATA_NEEDED: fMAX in MHz] in the spec list.
What is the difference between EPM3064ATC100-10NA and EPM3064ATC100-7N?
Both are MAX 3000A CPLDs in the same TQFP-100 package with 64 macrocells, but the EPM3064ATC100-7N is a 7 ns (faster) speed grade while the EPM3064ATC100-10NA is the 10 ns speed grade. Faster speed grades (lower tPD number) command a higher unit price and have tighter timing margins. Pin-to-pin compatibility across speed grades allows -7N to be used as a drop-in upgrade for -10N/NA applications, with timing re-validation required.
When should I choose EPM3064ATC100-10NA over EPM3032ATC44-10?
Choose EPM3064ATC100-10NA when you need 64 macrocells and 66 user I/Os in a TQFP-100 footprint; choose EPM3032ATC44-10 only when 32 macrocells and 36 I/Os in a TQFP-44 package are sufficient. The EPM3064ATC100-10NA also supports more I/O voltage standards via its MultiVolt interface and offers 1,250 usable gates versus 600 for the EPM3032. If your design requires more than 32 macrocells, the EPM3064ATC100-10NA is the natural choice within the MAX 3000A family.
What is the best drop-in replacement for EPM3064ATC100-10NA?
The closest drop-in replacement for the EPM3064ATC100-10NA is the EPM3064ATC100-10N (same MAX 3000A die, same TQFP-100 package, identical 10 ns speed grade, same 64 macrocells). For higher speed, the EPM3064ATC100-7N is a pin-compatible 7 ns upgrade. For more logic capacity in the same package, the EPM3128ATC100-10 (128 macrocells) and EPM3256ATC100-10 (256 macrocells) are pin-compatible MAX 3000A upgrades with the same TQFP-100 footprint.
EPM3064ATC100-10NA vs EPM3064ATC100-10N - which is better for my design?
Functionally, the EPM3064ATC100-10NA and EPM3064ATC100-10N are identical - both are MAX 3000A CPLDs with 64 macrocells, 66 I/Os, and a 10 ns tPD in the TQFP-100 package. The only difference is that the 'NA' suffix designates lead-free RoHS-compliant lead finish, while the 'N' suffix indicates tin-lead finish. For new designs targeting RoHS compliance (EU WEEE/RoHS 2011/65/EU), choose the 'NA' order code; for legacy designs accepting SnPb finish, either works electrically.
Can I replace EPM3064ATC100-10NA with a MAX II device?
No, the EPM3064ATC100-10NA is not pin-compatible with MAX II CPLDs (e.g. EPM240, EPM570). MAX II devices use a different package family (typically TQFP-100 with different pin assignments or QFN-100), different I/O standards, and a different JTAG/ISP implementation. A drop-in replacement must share both the package AND the pin assignments; MAX II is the architectural successor but is NOT a footprint-compatible upgrade.
Where can I download the EPM3064ATC100-10NA datasheet PDF?
The official Altera MAX 3000A Programmable Logic Device Family Data Sheet PDF is available at https://www.alterasemi.com/datasheet/alterasemi/EPM3064ATC100-10N.pdf (the family datasheet covers EPM3064ATC100-10NA as a member of the family). For the most up-to-date document, search 'MAX 3000A datasheet' on the Intel FPGA support site. The datasheet includes DC characteristics, AC timing, pinout, and programming specifications.
Where can I find the EPM3064ATC100-10NA pinout?
The EPM3064ATC100-10NA pinout is documented in the MAX 3000A family datasheet section 'TQFP-100 Pin-Out'. Pin 1 is at the top-left of the package when the notch/dot marker is oriented up. The TQFP-100 pin assignment is also shown in Quartus II device pinout views (Pin Planner). All 100 pins are listed in the pinout array on this product page.
What software is needed to program EPM3064ATC100-10NA?
The EPM3064ATC100-10NA is programmed using Altera Quartus II (legacy versions 9.x-13.0sp1) or the original MAX+PLUS II toolchain. The compiled JEDEC file is loaded via JTAG (IEEE 1149.1) using a USB-Blaster or ByteBlaster download cable. Quartus II Web Edition (free) supports MAX 3000A device fitting. Programming is in-system per IEEE Std. 1532, allowing reconfiguration on a populated PCB.
What is the difference between EPM3064ATC100-10NA and EPM7064AETI100-7N?
Both are Altera CPLDs in the TQFP-100 package, but they belong to different families with different logic capacities and supply voltages. The EPM3064ATC100-10NA is MAX 3000A (3.3V core, 64 macrocells, 10 ns tPD, commercial 0-70C grade). The EPM7064AETI100-7N is MAX 7000AE (5.0V core, 64 macrocells, 7 ns tPD, industrial -40-85C grade). They are NOT drop-in compatible because of different supply rails and different macrocell/I/O pin assignments within the same physical package.

Guia de seleção

Choose the EPM3064ATC100-10NA when you need a 64-macrocell, 66-I/O CPLD in TQFP-100 with a 10 ns pin-to-pin delay and lead-free RoHS-compliant finish. It is the right choice for 3.3V core / multi-voltage I/O bus decoding, glue-logic integration, and instant-on sequencing applications where deterministic timing matters. Choose the EPM3064ATC100-10N only for legacy tin-lead assembly lines that explicitly require non-RoHS finishes. Choose the EPM3064ATC100-7N when 7 ns tPD is required for tighter timing margins. For designs requiring more than 64 macrocells in the same TQFP-100 footprint, upgrade to the EPM3128ATC100-10 (128 macrocells) or EPM3256ATC100-10 (256 macrocells). Do not use MAX II devices as drop-in replacements - they require different packages and pin assignments.

Notas de projeto

The EPM3064ATC100-10NA requires two distinct supply rails: VCCINT (3.3V core, typically ~50-150 mA depending on utilization and toggle rate) and one or more VCCIO bank supplies (2.5V / 3.3V / 5.0V per I/O bank). Place a 0.1 uF ceramic decoupling capacitor adjacent to every VCCINT and VCCIO pin, plus a single 10-47 uF bulk tantalum or ceramic capacitor near the package. Use a star-ground topology or a continuous ground plane to avoid supply-induced jitter on the global clock nets.

Route the JTAG signals (TCK, TMS, TDI, TDO) as a short daisy-chain or star with 22-33 ohm series termination near the driving pin. Keep JTAG traces away from switching I/O and clock nets to minimize capacitive coupling. The TQFP-100 package has 0.5 mm lead pitch, which requires careful PCB land-pattern design with solder mask slivers between pads to prevent solder bridges during reflow.

Do not connect unused I/O pins to floating traces - configure them as outputs driving a known logic level (typically LOW) in the Quartus II device settings to minimize power consumption and switching noise. Ensure all four dedicated input pins (GCLK1, GCLK2, OE1, OE2, CLR) are tied to a valid logic level (active HIGH or LOW via 10 kohm pull-up/pull-down) if unused, since floating dedicated inputs can cause unpredictable behavior. Verify that VCCIO bank voltages match the connected bus drivers to avoid input over-voltage stress.
