EPM3064ATC100-7N Tóm tắt

The Altera (Intel) EPM3064ATC100-7N is a high-performance, low-cost CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 3000A family, featuring 64 macrocells, 2 Logic Array Blocks (LABs), and 66 user I/O pins in a 100-pin TQFP package. Built on the legacy MAX architecture with 3.3-V in-system programmability (ISP) via the IEEE Std. 1149.1 JTAG interface, this device delivers pin-to-pin propagation delays as fast as 7.5 ns and supports internal counter frequencies up to 166.7 MHz in the -7 speed grade, with usable logic capacity up to 1,250 gates.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that sits between simple PAL/GAL chips and large FPGAs in the programmable logic hierarchy (CPLD -> PLD -> programmable logic -> integrated circuit). CPLDs are characterized by instant-on non-volatile configuration (typically EEPROM or flash), predictable timing with deterministic pin-to-pin delays, and are well suited for glue logic, bus interfacing, state-machine control, and I/O expansion. Unlike SRAM-based FPGAs, CPLDs do not require external boot memory, simplifying board design and shortening time-to-market.

Key features include 3.3-V core operation with separate VCCIO banks that can be powered at 3.3 V or 2.5 V for mixed-voltage I/O compatibility, built-in JTAG boundary-scan test (IEEE Std. 1149.1), and ISP compliance with IEEE Std. 1532 for concurrent programming between multiple PLD vendors. The architecture combines a programmable interconnect array, macrocells with configurable registers, and a global routing network, providing up to 10,000 usable gates and predictable timing across operating conditions.

The -7 speed grade supports 7.5 ns pin-to-pin delays with 166.7 MHz internal counters, making the part suitable for high-speed bus arbitration, address decoding, and synchronous state-machine applications. The device operates across the standard 0 °C to 70 °C commercial temperature range with 3.3-V VCCINT, while VCCIO flexibility enables interface to 2.5-V downstream logic without external level shifters.

Typical applications include industrial control systems, automotive body electronics, telecommunications infrastructure, peripheral interface bridging, and legacy 5-V-to-3.3-V system upgrades where the CPLD absorbs the glue logic. The non-volatile configuration and deterministic timing make it ideal for boot-time-critical tasks such as clock generation reset sequencing and power-rail control.

When designing with this device, ensure that the JTAG chain is correctly ordered if multiple devices share TCK/TMS/TDI/TDO, and add 0.1 µF decoupling capacitors adjacent to every VCCINT and VCCIO pin. For high-speed designs, follow Altera application-note guidelines for signal integrity on clock and global clear nets.
