EPM7128ATC100-10 Présentation
A Complex Programmable Logic Device (CPLD) is a non-volatile, flash- or EEPROM-backed programmable logic IC that combines the instant-on behavior of a PAL/GAL with the integration density of an FPGA. CPLDs sit between discrete glue logic and larger FPGAs in the programmable logic hierarchy, providing deterministic, fast propagation delays (typically under 10 ns) and high pin-to-pin timing predictability for bus-interface, address-decode, and state-machine tasks.
The MAX 7000A family is one of Altera's most widely deployed 3.3V CPLD families. Per the manufacturer datasheet, the EPM7128ATC100-10 supports 3.3V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, eliminating the need for a separate programmer. Its MultiVolt I/O interface lets the 3.3V core drive 5.0V, 3.3V, and 2.5V logic levels, allowing direct interfacing with legacy 5V peripherals, modern 3.3V ASICs, and lower-voltage LVCMOS devices on the same board.
Architecturally, the device integrates 2.5K usable gates, 128 macrocells, a programmable interconnect array (PIA), and four LABs. Each macrocell contains a programmable AND/OR/registered-logic array plus a flip-flop, supporting combinatorial or registered outputs with configurable polarity. The 100-pin TQFP package (designator "TC100") is one of several package options offered across the MAX 7000A family.
Typical applications include PCI bus interface glue logic, address decoding for microprocessors, state-machine and sequencer controllers, peripheral bus adapters, and legacy 5V-to-3.3V level shifting in industrial control, telecom, and embedded computing systems.
When designing, ensure that ISP/JTAG signals (TCK, TMS, TDI, TDO) are routed cleanly and that unused I/O pins are configured as outputs or tri-stated to minimize in-rush current at power-up.

Applications typiques
EPM7128ATC100-10 convient pour 6 applications: PCI Bus Interface Glue Logic, Microprocessor Address Decoding, Legacy 5V-to-3.3V Level Shifting, State Machine and Sequencer Controllers, Peripheral Bus Adapters (ISA, VME, PC/104), Embedded Computing Glueless Peripherals.
PCI Bus Interface Glue Logic
The EPM7128ATC100-10's 4.5 ns pin-to-pin logic delay and 33 MHz PCI bus compatibility make it well suited for implementing PCI target interface glue logic, address decode, and command/byte-enable generation. With 128 macrocells it can host a complete 32-bit PCI target state machine plus several custom registers. Placed between the PCI bus connector and a downstream ASIC, the device consumes negligible power (under 300 mW typical at 3.3V) and provides deterministic timing critical for PCI bus cycles. Compared to discrete 74-series logic, the CPLD integration reduces PCB area by 5-10x while preserving the 10 ns worst-case latency budget.
Recommandé
Microprocessor Address Decoding
The 128 macrocells of the EPM7128ATC100-10 are ideal for complex memory and peripheral address-decoding tasks in 16-bit and 32-bit microprocessor systems. Each macrocell implements a sum-of-products term that maps one or more address lines plus chip-select qualifiers to a single decode output. With 68 user I/O pins, the device can decode multiple banks of memory, peripherals, and I/O devices simultaneously while leaving dedicated JTAG pins for in-system reprogramming. The 4.5 ns propagation delay ensures zero-wait-state operation for processors up to 50 MHz bus frequency, and the MultiVolt I/O interface allows direct 5V-to-3.3V interfacing with legacy MCUs.
Recommandé
Legacy 5V-to-3.3V Level Shifting
The EPM7128ATC100-10's MultiVolt I/O interface supports 5.0V, 3.3V, and 2.5V logic levels simultaneously, allowing it to act as a bidirectional level shifter between legacy 5V peripherals and modern 3.3V ASICs or processors. Each I/O bank can be configured independently, enabling mixed-voltage designs on a single chip. Typical use cases include interfacing 5V sensors or industrial buses to 3.3V microcontrollers without external level-translator ICs, reducing BOM cost and PCB area. The 3.3V core consumes approximately 50% less power than equivalent 5V-only CPLDs while preserving full 5V tolerance on the I/O pins.
Recommandé
State Machine and Sequencer Controllers
CPLDs excel at implementing deterministic finite state machines, and the EPM7128ATC100-10's 128 macrocells support FSMs of substantial complexity including multiple parallel state machines with shared inputs. Per the manufacturer datasheet, each macrocell includes a flip-flop for registered outputs, enabling fully synchronous state-machine designs with predictable timing. Industrial sequencer applications (machine tool controllers, conveyor logic, test equipment) benefit from the 10 ns pin-to-pin delay for fast event response. The non-volatile EEPROM configuration means the sequencer state at power-on is deterministic, eliminating the boot-time variability of SRAM-based FPGAs.
Recommandé
Peripheral Bus Adapters (ISA, VME, PC/104)
Legacy peripheral bus standards (ISA, VME, PC/104) still see widespread use in industrial and embedded computing, where the EPM7128ATC100-10 serves as a compact bus bridge and adapter. The device can implement custom address mapping, interrupt steering, and DMA handshaking for adding modern peripherals to legacy bus systems. The 100-pin TQFP package provides 68 user I/O pins, sufficient for full 16-bit data plus 24-bit address plus control signals. Quartus II software supports the part for design entry, simulation, and JTAG programming using USB-Blaster or ByteBlaster cables.
Recommandé
Embedded Computing Glueless Peripherals
The EPM7128ATC100-10 enables microprocessors and microcontrollers to interface with peripherals that lack a native bus interface, implementing custom protocols, FIFO buffers, and timing generators. With 128 macrocells and 68 I/O pins, designers can implement multiple peripherals (custom UARTs, SPI controllers, PWM generators, capture timers) on a single CPLD, reducing system cost and board area. The 4.5 ns propagation delay supports real-time protocol timing for high-speed serial interfaces. EEPROM-backed configuration means peripherals come up instantly at power-on, critical for boot-loader and system-controller roles.

Principaux différenciateurs
- MultiVolt I/O interface for mixed-voltage designs (vs MAX 7000S EPM7128STC100-15)
- 4.5 ns pin-to-pin delay with 227.3 MHz internal frequency (vs EPM7064AETC100-10)
- Standard 10 ns speed grade for legacy designs (vs EPM7128AETC100-7 (7 ns speed grade))
Notes de conception
The EPM7128ATC100-10 requires a clean 3.3V core supply with at least 100 mA of headroom for ISP programming current spikes. Place a 100 uF bulk capacitor and a 0.1 uF decoupling capacitor within 1 cm of each VCC pin (TQFP-100 has multiple VCC pins distributed along all four sides). For mixed-voltage designs, route 5V tolerant I/O banks separately from 3.3V-only banks to prevent back-powering through I/O pins.
Route the JTAG signals (TCK, TMS, TDI, TDO) as a controlled-impedance group with series 33 ohm damping resistors near the CPLD. Keep JTAG traces away from switching signals and add a ground guard on both sides. For in-system programming via USB-Blaster or ByteBlaster, expose a 2x5 0.1 inch JTAG header on the PCB with VCC sense pin connected to the CPLD's 3.3V rail for buffer reference.
Do not leave unused I/O pins floating; configure them as outputs driving logic-low in the Quartus project to minimize in-rush current at power-up. Avoid using GCLK (global clock) pins for non-clock signals, as this prevents the macrocell from using the fast global clock network. When migrating from the 5V MAX 7000S to the 3.3V MAX 7000A, verify I/O voltage compatibility - the MAX 7000A core is 3.3V-only even though its I/O pins are 5V tolerant.
Informations de conformité
RoHS and lead-free status not confirmed in verified web data - consult Rochester Electronics documentation or original Altera datasheet. The -10N suffix variants (EPM7128AETC100-10N) are typically lead-free/RoHS-compliant per Altera/Intel naming convention. AEC-Q100 is not applicable as this is a logic device, not an automotive-qualified part.
