EPM7128BTC144-7 - 128-Macro MAX 7000B CPLD, 144-TQFP | Intel
MPN: EPM7128BTC144-7 ✗ Cuối đờiEPM7128BTC144-7 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device positioned between discrete PAL/GAL devices and larger FPGAs. The MAX 7000B series is built on Altera's second-generation MAX architecture, which uses an enhanced connective array of fast, uniform interconnect channels routed to Logic Array Blocks (LABs) of 16 macro cells each. CPLDs retain their configuration in on-chip EEPROM, so they power up instantly without external boot memory - a key reason they remain popular for control-plane logic and deterministic timing paths.
Key features of the EPM7128BTC144-7 include 128 macro cells, 100 user I/O pins (per the 144-pin TQFP package option), a pin-to-pin delay of 7.5 ns, an internal global clock network with up to 6 dedicated inputs, and per-macro-cell configurable clear, preset, clock-enable, and OE controls. The device supports IEEE 1149.1 boundary-scan test, multiVolt I/O interfacing (5.0 V, 3.3 V, 2.5 V mixed-voltage systems), and a JTAG-based ISP flow that lets the board be re-programmed without removing the part. The 144-TQFP footprint provides ample ground and power pins for noise-sensitive designs.
The MAX 7000B architecture combines an EEPROM-backed configuration memory with a continuous FastTrack interconnect that links every LAB to every I/O pin through row and column channels. Each macro cell contains a programmable AND/OR/registered array plus an output cell with slew-rate, open-drain, and tri-state controls. This uniform fabric gives consistent timing across the device - making the EPM7128BTC144-7 well-suited to deterministic, latency-bounded applications such as bus arbitration, address decoding, and asynchronous interface bridging where FPGAs add unnecessary cost and boot complexity.
Typical applications include bus-interface glue logic between microcontrollers and peripherals, address decoding in 8/16/32-bit embedded systems, state-machine controllers in industrial automation, peripheral expansion for legacy I/O ports, and pin-level logic translation between mixed-voltage buses. Designers frequently pair the part with microcontrollers such as the 8051, ARM7, or Cortex-M0 families to offload real-time decode and protocol-conversion tasks.
When designing with this CPLD, place decoupling capacitors on every VCC/GND pair near the package and ensure JTAG TCK does not exceed 10 MHz for reliable ISP. The 144-TQFP package has moderate thermal dissipation; however, since the MAX 7000B core draws very low quiescent current, no heatsink is normally required. Pay close attention to the I/O bank VCCIO voltage to match the logic levels of the surrounding system.

Ứng dụng tiêu biểu
EPM7128BTC144-7 phù hợp cho 6 Áp dụngs: Bus Interface and Address Decoding, Industrial State-Machine Controllers, Legacy Peripheral Expansion, Communication Protocol Bridging, Test and Measurement Instrumentation, Aerospace and Avionics Subsystems.
Bus Interface and Address Decoding
The EPM7128BTC144-7 is ideal for address decoding and bus-interface glue logic between microcontrollers, memory, and peripherals in 8/16/32-bit embedded systems. Its 128 macro cells easily handle 16-bit address-decode trees with multiple chip-select outputs and interrupt-acknowledge logic. The 7.5 ns pin-to-pin delay keeps decode-to-chip-select latency under two system clock cycles at 50 MHz, and the 100 user I/Os provide ample chip-select fan-out for SDRAM, Flash, and peripheral banks. MultiVolt I/O support lets the part bridge 5.0 V and 3.3 V buses without external level shifters.
Được đề xuất
Industrial State-Machine Controllers
In industrial automation and motor-control systems the EPM7128BTC144-7 provides deterministic state-machine control for stepper, BLDC, and solenoid sequencing. The EEPROM-backed configuration guarantees instant power-up into a known state - critical for safety interlocks and machine reset behavior - without external boot ROM. The commercial 0C to +90C operating range suits factory-floor enclosures, and the 144-TQFP package offers generous ground pins for noise immunity near motor-driver switching nodes. Designers use the 100 user I/Os to drive opto-isolated enable lines and read back limit-switch status.
Được đề xuất
Legacy Peripheral Expansion
The EPM7128BTC144-7 is a go-to expansion device for adding parallel ports, ISA-style buses, or legacy interfaces to modern microcontrollers and SoCs. With 128 macro cells it can emulate multiple 8255 PPI ports, generate timing waveforms, and de-multiplex address/data buses. The JTAG ISP interface lets firmware engineers update peripheral behavior in the field without board rework. The 144-TQFP provides 100 user I/Os - more than enough for 8-bit bidirectional data plus 16-bit address plus control signalling on a single chip.
Được đề xuất
Communication Protocol Bridging
The EPM7128BTC144-7 is widely used to bridge between asynchronous protocols (UART, SPI, I2C) and synchronous parallel buses in networking and telecom equipment. Its 7.5 ns pin-to-pin delay supports UART-to-parallel conversion at baud rates up to 921,600 bps with no flow-control loss, while the deterministic timing makes it ideal for SPI-to-parallel bridges feeding DSP and FPGA signal chains. The MAX 7000B LAB structure provides uniform delay across all paths, simplifying multi-protocol bridging where timing skew would otherwise degrade data integrity.
Được đề xuất
Test and Measurement Instrumentation
In bench-top test equipment and ATE fixtures the EPM7128BTC144-7 implements pattern generators, timing controllers, and DUT interface conditioning. Its 126.6 MHz counter frequency supports digital pulse generation with 8 ns resolution, sufficient for characterizing low-speed serial protocols and power-rail sequencing. The JTAG interface is exploited for both ISP and board-level boundary-scan tests per IEEE 1149.1. The 144-TQFP footprint allows the part to be placed close to connector pin electronics, minimizing trace-length skew on stimulus lines.
Được đề xuất
Aerospace and Avionics Subsystems
Although the EPM7128BTC144-7 is the commercial-temperature variant, its MAX 7000B core architecture is used in non-flight-critical avionics subsystems for cockpit display driving, sensor conditioning, and actuator interface logic. The EEPROM configuration ensures immediate deterministic boot - a requirement in DO-178-relevant avionics where FPGA boot time is unacceptable. Designers pair it with radiation-tolerant SRAM or shielding for fault-tolerant designs. For flight-critical paths, the MIL-spec EPM7128BMC144-7 (-55C to +125C) is the appropriate orderable variant.

Ghi chú thiết kế
The EPM7128BTC144-7 requires two supply rails: VCCINT at 2.5 V for the core logic and VCCIO at 2.5 V / 3.3 V / 5.0 V for each of the four I/O banks. Place a 0.1 uF decoupling capacitor within 5 mm of every VCCINT/VCCIO pin and a 10 uF bulk tantalum or ceramic capacitor near the package to suppress switching transients during ISP programming. The MAX 7000B core draws very low quiescent current (typical ICCSTANDBY < 100 uA) so no heatsinking is required even with all 100 user I/Os switching simultaneously.
Route JTAG signals (TCK, TMS, TDI, TDO) with 50 ohm controlled impedance and keep TCK trace shorter than 100 mm to avoid signal-integrity issues at high ISP clock rates. Place the JTAG header or test points on the same board edge as the CPLD to minimize stub lengths. If the 144-TQFP footprint is shared with an MAX 7000AE variant, double-check the VCCINT pin voltage - the AE variant requires 3.3 V and is NOT a drop-in replacement.
A common pitfall is selecting the wrong speed-grade suffix: -7 = 7.5 ns / 126.6 MHz, -10 = 10 ns / 100 MHz. Mixing -7 and -10 in a multi-CPLD design creates timing-skew bugs that surface only under temperature cycling. Also, the commercial-temperature EPM7128BTC144-7 must not be used in industrial applications - order EPM7128BTI144-7 instead. Finally, do not apply 5 V to any MAX 7000B I/O when VCCIO is below 3.3 V, or the input clamp diodes will forward-conduct.
When using the EPM7128BTC144-7 as a clock buffer or address decoder driving long bus traces, enable slew-rate control on the relevant output macro cells (slow slew rate for low-noise buses, fast slew for high-speed point-to-point links). Enable the bus-hold circuit on unused I/O pins to prevent floating inputs that can draw milliamps of shoot-through current. For multi-board designs, place a 33 ohm series-termination resistor on each clock output driving off-board.
