EPM3064ATC100-10N 概述
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs/galo PALs and higher-density FPGAs in the programmable logic hierarchy. Within power management and glue-logic designs, CPLDs are typically used for I/O expansion, bus interfacing, address decoding, state-machine control, and power-up sequencing rather than DSP or large data-path processing. The MAX 3000A family is the entry-level EEPROM-based CPLD line from Altera/Intel, characterized by low cost, low static power, deterministic timing, and instant-on capability - making it well-suited for cost-sensitive industrial and consumer designs.
Key features of the EPM3064ATC100-10N include 1,250 usable gates, 64 macrocells distributed across 2 LABs, 66 I/O pins, a 10 ns tPD (logic-array block-to-output) propagation delay, and a 5 ns global clock setup time. The device supports MultiVolt I/O, allowing interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic without external level shifters. JTAG boundary-scan test (BST) is built-in, enabling structural test access for production board test and in-field firmware updates.
The architecture combines a programmable AND/OR array with a fixed OR array feeding 64 macrocell flip-flops, each with configurable product-term allocation. The on-chip EEPROM configuration cell is rated for a minimum of 100 program/erase cycles, with security bits to protect the design IP from readback. The JTAG controller handles ISP, and the device retains its configuration through power cycles with zero boot latency.
Typical applications include I/O expansion and level translation in industrial control boards, address decoding and wait-state generation for legacy microprocessors, glue logic between ASICs and processors in telecom/networking equipment, peripheral controllers (UART, SPI, I2C bridges) in embedded systems, and configuration sequencing for multi-rail FPGA/MCU power-up.
When designing with this part, observe the 3.3 V core supply tolerance (3.0 V to 3.6 V), use a low-impedance ground plane under the TQFP package, and route JTAG signals (TCK, TMS, TDI, TDO) with impedance-controlled traces for reliable ISP at production. The 100-pin TQFP requires careful fanout on 4-layer or higher PCBs.

典型应用
EPM3064ATC100-10N 适用于 7 应用s: Industrial Control I/O Expansion and Glue Logic, Address Decoding and Wait-State Generation, Peripheral Bridging (UART, SPI, I2C, GPIO), Telecom and Networking Equipment Glue Logic, FPGA/Multi-Rail Power-Up Sequencing, Consumer Electronics Display and Interface Control, Legacy Design Maintenance and Field Replacement.
Industrial Control I/O Expansion and Glue Logic
The EPM3064ATC100-10N is widely deployed in industrial PLC and process-control boards where it provides 66 user I/O pins for I/O expansion, signal conditioning, and protocol bridging. Its 64 macrocells comfortably implement address decoding, wait-state generation, and peripheral multiplexing that would otherwise require 3-5 discrete 74-series logic packages. The non-volatile EEPROM configuration boots instantly without external flash, ensuring deterministic power-on behavior critical for industrial safety systems. According to the MAX 3000A datasheet, the device tolerates 3.0 V to 3.6 V supply variation and supports industrial MultiVolt I/O from 1.8 V to 5 V, eliminating level shifters on mixed-voltage backplanes.
推荐
Address Decoding and Wait-State Generation
In legacy microprocessor boards (x86, 68k, MIPS), the EPM3064ATC100-10N implements chip-select decoding and wait-state insertion that would otherwise require multiple PAL/GAL devices. Its 10 ns tPD keeps decode latency well below typical memory-access windows, while the deterministic continuous-connection architecture guarantees no timing variation across routing densities. Each macrocell's product-term allocator enables complex min-term decoding in a single device. According to the manufacturer datasheet, JTAG ISP allows in-system re-decoding without removing the chip from the board - a major advantage over legacy fuse-link PALs in field-upgradeable designs.
推荐
Peripheral Bridging (UART, SPI, I2C, GPIO)
The EPM3064ATC100-10N excels as a low-cost protocol bridge between microcontrollers and peripherals when on-chip peripheral counts are exhausted. 66 I/O pins are sufficient to implement multiple SPI-to-UART, I2C-to-parallel, or GPIO-expander bridges concurrently, with the 64 macrocells handling all state-machine and timing logic. The 3.3 V core with 5 V-tolerant MultiVolt I/O means a single device bridges 1.8 V sensors and 5 V legacy peripherals without external shifters. According to the MAX 3000A datasheet, the device's hot-socketing capability allows live insertion on backplanes.
推荐
Telecom and Networking Equipment Glue Logic
In telecom line cards and networking switches, the EPM3064ATC100-10N provides hot-swap control, board-presence detection, LED driving, and clock muxing between redundant PHYs. Its non-volatile instant-on behavior is essential for hot-swappable modules that must present a defined state to the backplane immediately upon insertion. The 100-pin TQFP footprint offers enough I/O to monitor several SFP/SFP+ cages simultaneously. According to the manufacturer datasheet, the JTAG 1149.1 interface supports boundary-scan test for production board-test coverage on dense backplanes.
推荐
FPGA/Multi-Rail Power-Up Sequencing
The EPM3064ATC100-10N is commonly used as a power-supply sequencer for FPGAs, ASICs, and DSPs that require strict rail-on/rail-off ordering. Each macrocell can drive one PG (power-good) input, allowing the device to monitor up to 64 rails via external comparators and assert enables to downstream regulators with programmable delays. According to the MAX 3000A datasheet, the deterministic 10 ns tPD plus the absence of any boot latency makes this device ideal for sub-millisecond sequencing - faster than any MCU-based sequencer.
推荐
Consumer Electronics Display and Interface Control
The EPM3064ATC100-10N serves as an LCD/OLED timing controller, key-scan matrix decoder, and backlight-driver sequencer in consumer appliances and AV receivers. Its low unit cost (under $2 at qty 1000) and low static power make it attractive for cost-sensitive consumer designs where an FPGA would be overkill. According to the manufacturer datasheet, MultiVolt I/O allows direct connection to 1.8 V display panels and 3.3 V microcontrollers without external level shifters, reducing BOM cost by 4-6 components per board.
推荐
Legacy Design Maintenance and Field Replacement
For end-of-life industrial and military systems originally designed around MAX 3000A CPLDs, the EPM3064ATC100-10N continues to provide long-term supply support with no firmware changes required. Its pin-compatible predecessors (EPM3064ATC100-10, EPM3064ATC100-7N) are drop-in replacements on existing boards. According to the manufacturer datasheet, the JTAG ISP interface allows field reprogramming of installed units via test headers, extending the service life of legacy systems without board rework.

设计说明
The EPM3064ATC100-10N requires a 3.3 V core supply (VCCINT) within 3.0 V to 3.6 V. Decouple each of the 4 VCC pins (85 plus others per datasheet pinout) with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a single 10 uF bulk capacitor near the supply entry point. The MultiVolt I/O banks (VCCIO) can be driven from 1.8 V, 2.5 V, 3.3 V, or 5 V independently of VCCINT, but each bank must be tied to a single rail - mixing voltages within one bank is not permitted. According to the manufacturer datasheet, in-rush current during ISP programming can briefly reach 100 mA per VCC pin, so the regulator must source at least 500 mA peak.
The 100-pin TQFP uses 0.5 mm lead pitch and requires 4-layer PCB fabrication with a continuous ground plane under the package. Route JTAG signals (TCK pin 82, TMS pin 81, TDI pin 80, TDO pin 100) as a bus with matched lengths within 25 mm to avoid signal-integrity issues during in-system programming at high TCK rates. Provide a 4-pin JTAG header (TCK/TMS/TDI/TDO plus GND) on every board for production programming access. The exposed thermal pad is not present on this package - the TQFP-100 relies on lead-frame dissipation to ambient, which is adequate for the device's ~100 mA active current.
Because the EPM3064ATC100-10N has 66 user I/O pins, output-edge di/dt can be significant (8 mA typical per pin, 16 mA per pin during simultaneous switching). Use series damping resistors (22-33 ohm) on outputs driving long traces (>50 mm) or capacitive loads (>50 pF) to control ground bounce on the shared GND pins. According to the manufacturer datasheet, ground pins are scattered through the package (pins 11, 24, 35, 47, 59, 71, 95 plus others) and must all be connected to the ground plane with short vias to provide adequate return paths. Unused I/O pins should be configured as outputs driving low to minimize switching noise.
Three common pitfalls: (1) Do not confuse the EPM3064ATC100-10N (lead-free, RoHS) with the EPM3064ATC100-10 (tin-lead, non-RoHS) - they are drop-in electrically but not interchangeable on a RoHS production line; (2) Do not exceed 100 program/erase cycles on the on-chip EEPROM or the configuration memory will degrade - cache the JEDEC file and only reprogram when the design actually changes; (3) Do not leave JTAG pins floating - TMS and TDI must be pulled up to VCCIO via 10 kohm resistors to keep the JTAG state machine in a known state during normal operation. A floating TMS pin can place the device in unintended test modes.
