EPM7512BTC144-7 - 512-Macrocell MAX 7000B CPLD, 7.5ns TPD, 144-TQFP | Intel
MPN: EPM7512BTC144-7 ✗ Cuối đờiEPM7512BTC144-7 Tóm tắt
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. The MAX 7000B architecture is the second-generation Multiple Array MatriX (MAX) family and represents the non-volatile, in-system programmable branch of programmable logic, sitting between small discrete PAL/GAL devices and large SRAM-based FPGAs in the programmable logic hierarchy (PAL -> GAL -> CPLD -> FPGA -> programmable SoC). It uses EEPROM configuration cells that retain the design without external memory and supports the IEEE 1149.1 JTAG boundary-scan interface for in-system programming (ISP) and board-level test.
Key specifications include 512 macrocells across 32 logic array blocks (LABs), 212 maximum user I/Os (package-dependent), and a maximum propagation delay of 7.5 ns. The device supports MultiVolt I/O, JTAG ISP, and open-drain output options. Each macrocell contains a programmable AND/OR array with a configurable flip-flop, enabling implementation of complex combinatorial and sequential logic in a single chip. The on-chip ISP via JTAG eliminates the need for external PROM and supports field upgrades.
The MAX 7000B architecture uses a bipolar/CMOS process with EEPROM configuration, providing 100 program/erase cycles minimum and 20+ years of data retention. Each macrocell supports a wide range of flip-flop configurations (D, T, JK, SR) and the global OE/clock networks simplify synchronous design. The 144-TQFP package provides adequate thermal headroom for commercial 0C to 70C operation at typical logic frequencies.
Typical applications include bus-interface glue logic, peripheral interfacing, state-machine control, address decoding in legacy 5V systems, and bus-protocol bridging in industrial control equipment. Designers choose the EPM7512BTC144-7 for drop-in pin compatibility with earlier MAX 7000 / MAX 7000A designs needing higher density and faster tPD than 128-macrocell predecessors like the EPM7128 family.
A key design consideration is that the -7 speed grade (7.5 ns tPD) targets 5V operation; ensure VCCINT is decoupled with 0.1 uF ceramic capacitors near each supply pin. For new designs, consider migrating to the MAX II or MAX V families (lower power, instant-on), but the EPM7512BTC144-7 remains the drop-in choice for sustaining existing 5V MAX 7000B boards and field replacements.

Ứng dụng tiêu biểu
EPM7512BTC144-7 phù hợp cho 7 Áp dụngs: Legacy 5V Industrial Bus Interface Glue Logic, Address Decoding for Embedded Microprocessor Boards, State-Machine and Protocol-Bridging Controllers, VME/PCI Backplane Chip-Select Generators, Test Equipment Front-Panel and Timing Generators, Aerospace and Defense Legacy System Sustainment, Medical Imaging Front-End Pre-Processing.
Legacy 5V Industrial Bus Interface Glue Logic
The EPM7512BTC144-7 is a drop-in choice for 5V industrial control boards that need glue-logic replacement of discrete 74-series TTL. With 512 macrocells and 7.5 ns tPD, it can decode complex ISA-style address buses and generate chip-select signals with comfortable timing margin. MultiVolt I/O accepts 3.3V and 5V signaling directly. Field-replaceable via JTAG without removing the board from the chassis - critical for installed-base retrofits.
Được đề xuất
Address Decoding for Embedded Microprocessor Boards
The EPM7512BTC144-7's 512 macrocells and 120 user I/Os make it well-suited to multi-bank memory-mapped address decoding for PowerPC, 68k, or x86 embedded SBCs. 7.5 ns tPD supports 50 MHz bus operation without wait-state insertion. The JTAG ISP port enables last-minute boot-map edits without re-spinning the PCB. Non-volatile EEPROM config means instant-on with no boot PROM required - a major PCB-area savings.
Được đề xuất
State-Machine and Protocol-Bridging Controllers
For custom serial-protocol bridges (e.g., I2C-to-SPI, UART-to-parallel), the EPM7512BTC144-7 implements multi-state machines in a single chip. Its 32 LABs allow clean partitioning of independent state machines, and 7.5 ns tPD handles 50+ Mbps state transitions. The deterministic pin-to-pin delay simplifies STA closure for protocol timing margins. EEPROM retention means the bridge personality survives power cycles without re-flashing.
Được đề xuất
VME/PCI Backplane Chip-Select Generators
The 120 I/Os and 7.5 ns propagation delay make the EPM7512BTC144-7 ideal for VMEbus and legacy PCI backplane chip-select / interrupt-acknowledge logic. Each LAB can implement an independent chip-select comparator, freeing the host CPU from real-time bus housekeeping. MultiVolt I/O directly interfaces 5V VME and 3.3V PCI signaling without level shifters. Industrial-temp variant is preferred for chassis-mounted slots.
Được đề xuất
Test Equipment Front-Panel and Timing Generators
Test and measurement chassis benefit from the EPM7512BTC144-7's deterministic delay for front-panel switch-debouncing, encoder-reading, and timing-pulse generation. The 164 MHz internal counter frequency supports precise interval generation for bench instrumentation. Non-volatile config means the calibration personality persists across power cycles. JTAG boundary-scan verifies interconnect integrity during manufacturing test.
Được đề xuất
Aerospace and Defense Legacy System Sustainment
For sustaining fielded avionics, radar, and naval systems, the EPM7512BTC144-7 offers drop-in form/fit/function replacement of original MAX 7000B parts in long-lifecycle programs. Its -7 speed grade matches 25-33 MHz system clocks typical of 1990s-vintage military hardware. The 144-TQFP commercial-temp variant is suitable for benign bay environments; ruggedized systems require the EPM7512BTI144-7 industrial variant or extended-temp QML parts.
Được đề xuất
Medical Imaging Front-End Pre-Processing
The EPM7512BTC144-7 is well-suited to medical imaging front-end boards that pre-process detector arrays before the data hits an FPGA or DSP. Its deterministic 7.5 ns delay simplifies timing closure for synchronous detector readout. 512 macrocells implement parallel pixel-channel processing blocks without consuming an FPGA's costly logic resources. Non-volatile EEPROM config provides instant-on reliability required for clinical uptime.

Ghi chú thiết kế
Estimated: VCCINT (2.5 V core) and VCCIO (3.3 V or 5.0 V I/O) require separate decoupling. Place one 0.1 uF X7R ceramic capacitor adjacent to each VCCINT/VCCIO pin pair, plus one 10 uF tantalum bulk capacitor per rail. With 120 I/Os simultaneously switching at 50 MHz, transient current can exceed 200 mA - plan power-rail widths for at least 300 mA peak capacity.
Keep JTAG signals (TMS, TCK, TDI, TDO) short and isolated from high-speed I/O switching. Use a 4.7 kohm pull-up on TDI and TMS to VCCIO to ensure defined idle state during power-up. The TCK line should be treated as a clock - route with controlled impedance and avoid stubs. Place the JTAG header near the CPLD to minimize parasitic capacitance.
Estimated: I/O banks on the MAX 7000B share VCCIO; mixing 3.3 V and 5.0 V devices on the same bank is NOT permitted. Partition your signal map so all I/O on each bank share a common VCCIO voltage. Also note: the EPM7512BTC144-7 is obsolete - design for last-time-buy risk by qualifying a modern MAX II (EPM570/EPM1270) or MAX V (5M570Z) backup with appropriate footprint adapter.
Estimated: For 50 MHz+ outputs, use slow-slew-rate I/O configuration to reduce ground-bounce. Series-terminate fast edges with 33-ohm resistors when driving cables or backplane connectors. The deterministic 7.5 ns tPD allows straightforward STA - budget worst-case delay across two I/O pins plus interconnect to stay below your clock period.
