EPM3128ATC100-10N - 128-Macrocell MAX 3000A CPLD, 10ns, TQFP-100 | Intel
MPN: EPM3128ATC100-10N ✗ Cuối đờiEPM3128ATC100-10N Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays with a central programmable interconnect matrix. CPLDs sit in the hierarchy between simple SPLDs (PALs/GALs) and larger FPGAs, offering deterministic, single-clock-cycle propagation delays and instant-on non-volatile configuration. The MAX 3000A family uses CMOS EEPROM configuration memory, IEEE Std. 1532-compliant in-system programmability (ISP), and belongs to the broader power-management and logic-IC semiconductor category.
Key features include 128 macrocells (2500 usable gates), 80 user I/O pins, an internal fMAX of 98 MHz (per the FPGAkey datasheet summary), 3.3 V VCCINT operation, and selectable 3.3 V or 2.5 V VCCIO banks for mixed-voltage I/O. The device is pin-compatible with other MAX 3000A 100-pin TQFP variants and supports JTAG-based boundary-scan testing alongside ISP. The non-volatile EEPROM cells eliminate the need for an external boot PROM and the part powers up instantly in a user-defined state.
Architecturally, the EPM3128ATC100-10N organizes its 128 macrocells into 8 Logic Array Blocks (LABs) of 16 macrocells each, connected through a Programmable Interconnect Array (PIA). Each macrocell contains a programmable AND/OR array feeding a configurable flip-flop with product-term clock, clear, and preset controls, supporting combinatorial, registered, and buried logic without consuming I/O.
Typical applications include I/O expansion and bus bridging on legacy glue-logic boards, address decoding and interrupt steering on industrial controllers, state-machine replacement in white-goods motor control, and pin-compatible MAX 3000A migration paths. Designers in factory automation, telecom line cards, and embedded computing rely on this part for deterministic timing and field-reprogrammability.
Designers should pay attention to VCCIO bank configuration: 3.3 V allows direct interface to 3.3 V logic, while 2.5 V setting enables 2.5 V system compatibility. The I/O pins share a common bus-friendly structure but each LAB region can source/sink up to 25 mA per pin with proper thermal management across the 100-pin TQFP (θJA around 35-40 °C/W depending on PCB copper). Avoid daisy-chaining JTAG; use a star topology for ISP chains longer than 4 devices.

Ứng dụng tiêu biểu
EPM3128ATC100-10N phù hợp cho 6 Áp dụngs: Address Decoding & Bus Bridging on Legacy Glue Logic, Industrial Control State Machine Replacement, Telecom Line-Card I/O Expansion, Embedded Computing Glue Logic in Single-Board Computers, White-Goods Motor Control and Appliance Logic, Test & Measurement Equipment Front-End Logic.
Address Decoding & Bus Bridging on Legacy Glue Logic
The EPM3128ATC100-10N fits address decoding and bus-bridging roles because its 10 ns pin-to-pin propagation delay is deterministic and its 128 macrocells provide abundant product-term capacity for complex Chip-Select and interrupt-steering logic. Placed between a 3.3 V microcontroller and asynchronous peripheral buses, the device replaces 4-8 discrete PAL/GAL chips with a single in-system-reprogrammable CPLD, cutting PCB area by up to 60%. The IEEE Std. 1532 ISP interface lets field technicians update decode maps without desoldering the part, a key advantage over legacy bipolar PALs.

Industrial Control State Machine Replacement
The EPM3128ATC100-10N is well-suited to replace discrete 74LS/74HC state machines in industrial controllers because its 98 MHz fMAX and 8 LABs support complex Moore/Mealy sequencers without microsequencer overhead. Its 80 user I/O pins map directly to typical PLC backplanes (32 inputs + 32 outputs + 16 control lines), and the non-volatile EEPROM means the controller boots into its last programmed state without an external boot PROM. The 3.3 V/2.5 V VCCIO flexibility lets the same board drive both 5 V-tolerant buffers (through level shifters) and native 2.5 V ASICs in mixed-voltage subsystems.
Được đề xuất
Telecom Line-Card I/O Expansion
Telecom line cards use the EPM3128ATC100-10N as a low-cost I/O expander because its 80 I/O pins comfortably aggregate 16-32 E1/T1 channels, and the 10 ns tPD preserves timing margins for HDLC framing at 2.048 Mbps. The CPLD's deterministic 1-cycle latency simplifies hardware protocol validation, while ISP allows field upgrades when adding new channel bonding features. Its commercial 0-70 °C range suits temperature-controlled central-office shelves, and the TQFP-100 package is compatible with automated optical-inspection assembly lines used by contract manufacturers.

Embedded Computing Glue Logic in Single-Board Computers
The EPM3128ATC100-10N integrates custom peripheral interfaces on Single-Board Computers (SBCs), where it bridges between ARM/SoC memory buses and legacy parallel ports, IDE interfaces, or custom FPGA mezzanine cards. Its 10 ns tPD adds less than one bus cycle of wait-state overhead at 100 MHz, and the 80 I/O pins handle simultaneous chip-select generation, interrupt aggregation, and GPIO expansion. The CPLD's 2500 usable gates give SBC designers headroom for last-minute feature additions without respinning the PCB.

White-Goods Motor Control and Appliance Logic
The EPM3128ATC100-10N is widely deployed in washing machines, dishwashers, and HVAC control boards as the central sequencer for brushless DC motor commutation and safety interlocks. Its non-volatile EEPROM configuration boots the appliance into a known state even after multi-day power loss, and the 80 I/O pins drive triac-fired heater banks, relay coils, and Hall-effect sensor inputs concurrently. The TQFP-100 footprint survives wave-solder-compatible reflow profiles used by high-volume appliance contract manufacturers.
Được đề xuất
Test & Measurement Equipment Front-End Logic
Test instruments use the EPM3128ATC100-10N to implement reconfigurable front-end routing matrices, trigger pattern generators, and scan-chain multiplexers. Its IEEE Std. 1532 ISP interface lets manufacturers ship instruments with field-upgradable trigger logic, extending product lifecycles without board rework. The 3.3 V/2.5 V VCCIO flexibility simplifies interfacing with modern ADCs and DACs while the 80 I/O count comfortably handles 32-channel multiplexer banks typical of mid-range oscilloscopes and data-acquisition systems.

Bảo phân biệt quan trọng
- Non-volatile EEPROM configuration enables instant-on operation (vsSRAM-based FPGAs (e.g., Cyclone series))
- Deterministic 10 ns pin-to-pin propagation delay (vsMicrocontroller-based glue logic)
- IEEE Std. 1532-compliant ISP eliminates external programmer (vsLegacy bipolar PALs (e.g., PALCE16V8))
- Dual VCCIO bank flexibility (3.3 V / 2.5 V) (vsSingle-supply CPLDs (e.g., MAX 7000S legacy))
Ghi chú thiết kế
Estimated: at VCCINT = 3.3 V and 80 I/O simultaneously switching at 5 MHz with 25 mA load per pin, the device core plus I/O current draw is approximately 80-120 mA. Use a 100 nF ceramic decoupling capacitor on every VCCINT pin and a 10 µF bulk capacitor near the package to suppress switching transients. Place decoupling capacitors within 3 mm of the supply pins to minimize inductance; vias to internal power planes must be at least 0.3 mm diameter for low ESL.
The 100-pin TQFP package (14 x 14 mm body, 0.5 mm pitch) requires a 4-layer PCB with continuous power and ground planes under the device to manage simultaneous switching noise. Route JTAG signals (TDI/TDO/TMS/TCK) as a daisy chain with 10 kΩ pull-ups on TMS and TCK, and place a 4.7 kΩ series terminator on TDO if the chain length exceeds 100 mm. For ISP chains longer than 4 devices, use a star topology to avoid signal integrity issues during programming.
Estimated: the TQFP-100 has a θJA of approximately 35-40 °C/W on a 4-layer JEDEC test board. At maximum operating ambient (70 °C commercial) and worst-case power dissipation of ~1 W (core + I/O), junction temperature rise is 35-40 °C above ambient, leaving 35-40 °C margin to the datasheet maximum Tj of 150 °C. For enclosed industrial enclosures with ambient above 50 °C, add thermal vias under the exposed pad region and ensure minimum 50 mm² of copper pour on both top and bottom layers.
Do not leave JTAG pins floating: TCK and TMS must be pulled to logic high through 10 kΩ resistors to keep the TAP controller in a defined state during power-up, otherwise the device may enter random JTAG states. VCCIO must ramp up before or simultaneously with VCCINT to prevent I/O latch-up; use a common power-sequencer IC or RC delay on the VCCINT rail if independent rails are used. Never exceed the maximum JTAG TCK frequency of 10 MHz for in-system programming.
