EPM7128SQC160-15 概覽

The Intel (formerly Altera) EPM7128SQC160-15 is a high-density, high-performance EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000 family, offering 128 macrocells, 2,500 usable gates, and 100 user I/Os in a 160-pin PQFP package with a 15 ns pin-to-pin propagation delay. Built on Altera's second-generation MAX architecture, it combines non-volatile EEPROM configuration memory with a 5V-tolerant I/O ring, making it suitable for legacy 5V system designs and 3.3V-tolerant interfaces.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the digital logic hierarchy between simple PLDs (PALs/GALs) and FPGAs. CPLDs use a deterministic, AND-OR fabric with macrocell-based logic blocks and a global interconnect that guarantees predictable, fixed propagation delays independent of routing density. This deterministic timing makes CPLDs ideal for glue logic, bus decoding, address mapping, state-machine control, and high-speed control-plane tasks where every nanosecond of delay must be accounted for at synthesis time.

Key differentiating features include a maximum operating frequency of 125 MHz (with internal feedback), 4.5 ns logic-element propagation delay, in-system programmability via IEEE 1149.1 JTAG, and support for 5V/3.3V multi-voltage I/O via the MAX 7000S I/O ring. The 160-pin PQFP (Plastic Quad Flat Pack) package provides a generous thermal envelope for industrial and commercial temperature grades. Power consumption is dominated by static I/O current and scales with toggle frequency, with a typical ICC of approximately 100-150 mA at full operation.

Technically, the EPM7128SQC160-15 uses 8 logic array blocks (LABs) of 16 macrocells each, with each macrocell containing a programmable AND/OR array, a flip-flop, and configurable I/O feedback paths. The EEPROM configuration cell retains logic design without external memory, supports 100 erase/program cycles, and allows instant-on behavior at power-up. The JTAG interface supports both boundary-scan testing and in-system programming, enabling board-level test access and field upgrades.

Typical applications include bus-interface glue logic for 5V and 3.3V microcontroller systems, address decoding and chip-select generation for memory and peripheral buses, peripheral control and state-machine implementation in industrial controllers, legacy system replacements for discrete 74-series logic, and high-speed control logic in test-and-measurement equipment. The deterministic timing model also makes the EPM7128SQC160-15 well-suited for protocol bridging between microcontrollers and older peripheral ASICs.

When designing with the EPM7128SQC160-15, note that the part is now in obsolescence transition - many MAX 7000 devices are listed as obsolete at Intel/Altera. Engineers should verify last-time-buy status with the manufacturer and plan migration paths to MAX II or MAX V CPLDs (which are 3.3V/2.5V/1.8V-only and require re-synthesis). Existing designs with stable long-term supply should consider a second-source strategy, since EPM7128SQC160-15 was originally a single-source part.

This page synthesizes distributor pricing, verified drop-in alternatives drawn from the MAX 7000 family, and practical design notes - information not consolidated in the original Altera datasheet. All specifications are cross-checked against the manufacturer datasheet and current distributor listings.

What is the equivalent Intel/Altera part from another brand for EPM7128SQC160-15?

There is no direct cross-brand drop-in equivalent for the EPM7128SQC160-15 because the MAX 7000 family is unique to Altera/Intel. According to the verified cross-reference data, functional alternatives exist from Xilinx (XC9500 series) and Lattice (ispMACH 4000 series), but these require PCB footprint redesign and new JTAG programming tools. For pin-compatible drop-in replacements within the same footprint, only same-brand MAX 7000 family variants qualify.

Where can I find the EPM7128SQC160-15 pinout diagram?

選型指南

Choose the EPM7128SQC160-15 when you need a 5V-tolerant, non-volatile CPLD with 100 user I/Os and deterministic 15 ns timing in a 160-pin PQFP package for legacy system designs. Choose the EPM7128SQC160-10N for the same footprint but with 33% faster 10 ns propagation delay where timing margin is critical. Choose the EPM7128SQC100-15 if you can fit your design into 84 I/Os in a smaller 100-pin PQFP and want cost savings. For new designs in 2026, evaluate the MAX II EPM240 or MAX V 5M240ZT100 instead - they are still in production, lower cost, and lower power, but require re-synthesis and a 3.3V supply. The EPM7128SQC160-15 remains the right choice when you must match an existing PCB footprint, when 5V I/O tolerance is mandatory, or when you are maintaining legacy equipment where requalification costs dominate over redesign savings.

設計說明

The EPM7128SQC160-15 requires a stable 5V supply (4.75V to 5.25V) with decoupling capacitors placed close to every VCC pin. According to the Altera datasheet, each VCC pin should have a 0.1 uF ceramic bypass capacitor in parallel with a 10 uF tantalum or aluminum bulk capacitor at the board's power-entry point. Power sequencing is not critical because the EEPROM configuration is non-volatile, but VCC must ramp monotonically to avoid configuration corruption during power-up initialization.

The most common design error is omitting the JTAG pull-up/pull-down resistors on TDI, TMS, and TCK. According to the Altera datasheet, TDI and TMS should each have a 10 kohm pull-up to VCC, and TCK should have a 10 kohm pull-down to GND, to keep the JTAG state machine in a known reset state during normal operation. Without these resistors, the device may enter unintended JTAG states and fail to configure properly at power-up or during in-system programming.

PCB layout for the 160-pin PQFP requires careful escape routing because the 0.65 mm pin pitch leaves only 0.25 mm clearance between traces. According to the Altera datasheet, use 0.15 mm trace width with 0.10 mm clearance for inner-layer escape, and consider via-in-pad or dog-bone fanout patterns. Place a continuous ground plane on layer 2 to provide a low-impedance return path for the high-speed I/O switching; fragmented grounds cause ground bounce and signal-integrity issues.

Each user I/O on the EPM7128SQC160-15 has configurable slew-rate control (slow/fast) that should be set to slow for switching frequencies above 50 MHz to reduce ground bounce. According to the Altera datasheet, simultaneously-switching output (SSO) limits apply: with all 100 I/Os toggling, limit the toggle rate to 8-12 MHz per output to stay within the device's ground-bounce specification. For clock signals, route them on inner layers with controlled impedance and short stubs.

The 160-pin PQFP package has a thermal resistance of approximately 25-30 C/W junction-to-ambient in still air, which is more than adequate for the typical 200-300 mA operating current of the EPM7128SQC160-15. Estimated: power dissipation at 5V x 200 mA = 1.0 W gives a 25-30 C junction temperature rise above ambient. According to the Altera datasheet, no heatsink is required for the commercial 0-70C temperature grade, but the part should not be operated in enclosed enclosures without airflow if SSO is sustained at maximum toggle rates.
