EPM7128STI100-10N - 128-Macrocell CPLD, 10ns, 100-pin TQFP | Altera
MPN: EPM7128STI100-10N ✗ Cuối đờiEPM7128STI100-10N Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays with a central programmable interconnect matrix. It sits between simple SPLDs (e.g., GAL22V10) and high-density FPGAs in the programmable logic hierarchy, offering deterministic timing, instant-on behavior from EEPROM configuration, and high I/O count with low power. The MAX 7000S family specifically uses second-generation MAX architecture fabricated in CMOS EEPROM technology, providing up to 5,000 usable gates across the family.
Key features include 84 user I/O pins (100-pin TQFP), 5 V core operation with 5 V tolerant I/O, JTAG boundary-scan test (BST) support, an open-drain output option on each I/O (in MAX 7000A variants), and a typical counter frequency up to 175.4 MHz. The 10 ns tPD supports glue-logic, interface bridging, and bus decoding at system clock rates up to approximately 100 MHz. Industrial temperature range is -40C to +85C.
Architecturally, the EPM7128STI100-10N is organized into 4 Logic Array Blocks (LABs), each containing 16 macrocells, with a programmable interconnect array (PIA) routing signals between LABs and to the I/O pins. The EEPROM configuration cell ensures zero-power non-volatile storage and instant power-on valid I/O within microseconds, a key advantage over SRAM-based FPGAs.
Typical applications include bus-interface bridging (e.g., PCI to local bus), address decoding and chip-select generation in microprocessor systems, glue-logic replacement of multiple 74-series TTL/CMOS parts, peripheral control in embedded designs, and state-machine implementation in industrial control. The 5 V I/O tolerance is particularly valuable for legacy 5 V system integration.
When designing with this part, account for the 5 V supply requirement (cannot directly interface with 3.3 V-only systems without level translation), ensure JTAG chain integrity if multiple devices share the TAP, and respect the I/O current-limit specifications when driving heavy loads.

Microprocessor Bus Decoding and Chip-Select Generation
The EPM7128STI100-10N is ideally suited for address decoding and chip-select generation in microprocessor and microcontroller systems. With 128 macrocells and 84 user I/Os in a 100-pin TQFP package, it can decode wide address buses (24+ bits) and generate individual chip-selects for memory banks, peripherals, and I/O devices. The 10 ns pin-to-pin delay ensures clean chip-select timing with zero wait-state operation at moderate clock rates. Its 5 V tolerance matches legacy 8051, x86, and 68k designs. The EEPROM-based non-volatile configuration means decoded logic is valid within microseconds of power-on, eliminating the FPGA-style configuration delay. Per the Altera datasheet, each macrocell provides product-term AND/OR arrays with programmable register/feedback paths, allowing complex decode equations like address AND chip-type AND strobe.

Legacy 5V Glue Logic Replacement
Replace clusters of 74-series TTL/CMOS glue-logic ICs (address latches, decoders, multiplexers, flip-flops) with a single EPM7128STI100-10N to reduce board area, BOM count, and improve design flexibility. The 128 macrocells and 84 I/Os absorb what would otherwise require 5-10 discrete packages. 5 V native supply matches 74LS, 74HC, 74F, and 74ABT logic families directly without level translation. The 10 ns tPD supports glue-logic timing in systems up to approximately 50 MHz. Industrial temperature grade (-40C to +85C) makes it suitable for factory-floor and outdoor embedded designs. JTAG in-system programmability lets engineers iterate logic without re-spinning the PCB - a key advantage for prototyping and field updates per Altera's MAX 7000S datasheet.

PCI / Local-Bus Interface Bridge
The EPM7128STI100-10N bridges legacy PCI (33 MHz, 5 V) to local processor or memory buses in embedded designs. Its 10 ns tPD supports 33 MHz PCI timing with margin, and the 5 V tolerant I/O directly interfaces PCI bus signals. 128 macrocells implement state machines for bus arbitration, transaction handling, and interrupt steering without external logic. 84 user I/Os accommodate the multiplexed address/data bus plus sideband control signals (FRAME, IRDY, TRDY, STOP, DEVSEL, REQ, GNT). Per Altera datasheet, the JTAG boundary-scan test (BST) support is invaluable for production board test of PCI-impedance-controlled designs. Industrial temperature grade supports harsh-environment embedded systems.

State Machine and Sequencer for Industrial Control
Implement complex multi-state controllers (e.g., motor-control sequencers, conveyor state machines, machine-tool controllers) in a single EPM7128STI100-10N. The 128 macrocells support large state machines with up to 64 states using one-hot encoding, while 84 I/Os interface to sensors, actuators, HMI panels, and communication ports. Industrial -40C to +85C temperature range handles factory-floor conditions including cabinet heat and outdoor enclosures. EEPROM non-volatile configuration provides instant-on valid outputs, critical for safety interlocks that must be active before software boots. The 10 ns tPD enables deterministic state-transition timing required for safety-critical sequencing. JTAG ISP supports in-field firmware updates via the JTAG chain without removing the board from service.

Peripheral Control and I/O Expansion
Expand I/O capability of microcontrollers, FPGAs, or SoCs that have insufficient native I/O count by using an EPM7128STI100-10N as a peripheral driver. Each of the 84 user I/Os can source/sink per Altera's DC specifications, supporting LED drivers, relay coils (with external transistors), keypad scanning matrices, and 7-segment display multiplexing. 5 V tolerance directly drives legacy 5 V peripherals. The CPLD offloads scan/keypad debounce logic, PWM generation, and display refresh from the main processor, freeing CPU cycles for application code. JTAG ISP enables rapid iteration of peripheral mappings. Industrial temperature grade suits automotive, military, and outdoor applications.

DSP / Data-Path Glue Logic in Test Equipment
In test and measurement instruments (oscilloscopes, logic analyzers, signal generators), the EPM7128STI100-10N provides glue logic between high-speed ADCs/DACs, FPGAs, and memory interfaces. The 10 ns tPD and 175.4 MHz max counter frequency support timing-critical signal routing, clock distribution, and trigger generation. 5 V tolerance interfaces legacy analog front-ends. 128 macrocells absorb timing-and-control state machines without burdening the main FPGA. The JTAG boundary-scan support enables full board-test coverage for ICT and flying-probe testers. Per Altera datasheet, the device supports up to 175.4 MHz counter frequencies, making it suitable for clock-divider, frequency-counter, and PWM-generator sub-functions.

Ghi chú thiết kế
The EPM7128STI100-10N requires a single 5.0 V supply. Per Altera datasheet operating requirements, VCC must rise monotonically during power-up and inputs may undershoot to -2.0 V for input currents less than 100 mA and periods shorter than 20 ns. Decouple VCC with a 0.1 uF ceramic capacitor placed within 5 mm of the package pins, plus a bulk 10-47 uF tantalum or low-ESR aluminum capacitor on the same rail. Estimated: ICC for an unloaded MAX 7000S device is typically 50-150 mA depending on logic utilization and clock rate - verify with actual design utilization via Quartus PowerPlay. Add a ferrite bead if the 5 V rail also feeds analog circuitry to isolate switching noise from the CPLD's internal EEPROM programming circuitry.
Route JTAG signals (TDI, TDO, TMS, TCK, TRST optional) as a daisy-chain if multiple devices share the TAP. Keep JTAG trace length under 150 mm and add 10 kohm pull-ups on TMS and TDI to prevent floating during reset. Per Altera MAX 7000S datasheet, the JTAG interface operates at typical TCK frequencies up to 10 MHz but is sensitive to signal integrity; avoid routing JTAG near clock or high-speed data lines. Exposed thermal pad on TQFP-100 packages should be soldered to a thermal pad on the PCB connected to a ground plane for heat dissipation. Ensure the ground plane is solid under the device with at least 4 vias stitching the top and bottom ground layers.
Estimated: At 128-macrocell full utilization with 100 MHz toggle rate, dynamic current consumption can reach 250-400 mA - confirm thermal budget using the Altera PowerPlay early power estimator before finalizing the PCB. Critical pitfalls to avoid: (1) Do not leave unused I/O pins floating - configure as outputs driving low or as inputs with internal pull-ups enabled in the Quartus pin assignment, because floating inputs may oscillate and draw excessive supply current. (2) Do not apply voltage to I/O pins before VCC ramps up - this can trigger EEPROM programming logic accidentally. (3) Do not use the device below 4.75 V or above 5.25 V - operation is not guaranteed outside this range. (4) Use the BSDL file from the Altera website for boundary-scan test integration; an incorrect BSDL will fail ICT.
