A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with a central interconnect. Within the broader taxonomy, the EPM3064ATI100-10 sits at: CPLD -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. MAX 3000A devices use EEPROM-based configuration cells, which retain the design without external memory and allow instant-on behavior at power-up, distinguishing them from SRAM-based FPGAs that require a boot sequence.
Key features of the EPM3064ATI100-10 include 64 macrocells organized into four Logic Array Blocks (LABs), 66 user I/O pins, 3.3 V single-supply operation, in-system programmability through JTAG (IEEE 1149.1), and PCI-compatible I/O signaling in the -4, -5, -6, -7, and -10 speed grades. The device also provides programmable interconnect, four user I/O banks, and open-drain or slew-rate-controlled output options for mixed-voltage environments.
The MAX 3000A architecture combines a programmable interconnect array with multiple LABs, each containing 16 macrocells built around EEPROM configuration memory. This EEPROM backing means designs load instantly at power-up with no boot PROM required, while the deterministic interconnect delivers predictable timing well suited to control logic, bus interfacing, and glue-logic replacement. Counter frequencies reach up to 227.3 MHz in faster speed grades.
Typical applications include PCI bus interface glue logic, address decoding and bus arbitration, state-machine controllers, I/O expansion for microcontrollers, and legacy board redesigns where a 5 V-tolerant, instant-on programmable device replaces discrete 74-series logic. The wide package and high I/O count make it well suited to interface bridging between processors, memory, and peripherals.
When designing with this device, ensure your JTAG chain is correctly ordered and that the I/O bank supply (VCCIO) matches the driven logic level, since 3.3 V outputs may need series resistors or level shifters when driving 5 V inputs. Confirm the -10 speed grade meets setup/hold margin for the slowest path in your design.

典型應用
EPM3064ATI100-10 適用於 6 應用s: PCI Bus Interface Glue Logic, Address Decoding and Bus Arbitration, State-Machine Controllers, I/O Expansion for Microcontrollers, Legacy 74-Series Logic Replacement, JTAG-Boundary-Scan Test Controllers.
PCI Bus Interface Glue Logic
The EPM3064ATI100-10 fits PCI bus interface glue logic because its 64 macrocells can implement the address decoding, command handling, and parity logic typical of PCI target devices, while the -10 speed grade satisfies the PCI Local Bus Specification 2.2 timing budgets. Its 3.3 V I/O banks are directly compatible with the PCI signaling environment. With 66 user I/Os, the device can multiplex address and data signals, drive interrupt lines, and arbitrate bus requests without external logic. The EEPROM-backed MAX 3000A architecture provides instant-on configuration, eliminating the boot delay of SRAM-based FPGAs.
推薦
Address Decoding and Bus Arbitration
The EPM3064ATI100-10's 64 macrocells and four Logic Array Blocks make it an efficient address decoder for processor and memory subsystems. Designers can map multiple address windows, generate chip selects with programmable wait-state insertion, and arbitrate DMA or bus-master requests in a single device. The deterministic 10 ns pin-to-pin delay simplifies worst-case timing analysis for asynchronous bus interfaces. Industrial temperature grade and 66 I/Os make it suitable for embedded backplanes where multiple peripherals must share a common address/data bus with predictable response times.
推薦
State-Machine Controllers
The EPM3064ATI100-10's macrocell architecture is well suited to implementing complex state machines for industrial control, motor sequencing, and protocol handling. Each macrocell includes a flip-flop with programmable clock, reset, and enable controls, allowing designers to encode large FSMs efficiently. The EEPROM-backed configuration ensures the controller enters its defined state immediately at power-up, which is critical for safety interlocks and deterministic sequencing. With industrial temperature rating and JTAG boundary-scan support, the device supports both harsh environments and modern testability requirements.
推薦
I/O Expansion for Microcontrollers
The EPM3064ATI100-10 expands microcontroller I/O count by translating limited GPIO pins into many additional parallel outputs through external memory-style interfaces. Designers can connect the CPLD to an SPI, I2C, or parallel bus from the host MCU and expose dozens of additional pins with programmable direction, pull-ups, and interrupt capability. With 66 user I/Os, the device can replace multiple 74-series logic packages while adding configurability. The 100-pin TQFP package is easy to hand-prototype and the JTAG interface simplifies in-field reprogramming of pin mappings and timing.
推薦
Legacy 74-Series Logic Replacement
The EPM3064ATI100-10 consolidates multiple 74-series TTL/CMOS logic packages into a single programmable device, reducing board area, power, and BOM cost in legacy designs. Functions such as address latches, bus transceivers, multiplexers, decoders, and shift registers can all be absorbed into the 64-macrocell fabric. The industrial temperature grade and 3.3 V operation fit directly into modern low-voltage retrofits of older 5 V systems when paired with level shifters. Migration to the part often reduces part count by 5x-10x on logic-heavy boards.
推薦
JTAG-Boundary-Scan Test Controllers
The EPM3064ATI100-10 implements custom JTAG controllers and boundary-scan test infrastructure for board-level interconnect verification. Its built-in IEEE 1149.1 TAP controller and user-defined BSR cells allow the device to act as both a JTAG target and a test master for downstream clusters. With 64 macrocells and 66 I/Os, it can drive a full JTAG chain of multiple devices while implementing PASS/FAIL aggregation logic. Industrial temperature rating supports production test systems and field diagnostics in harsh environments.

- Industrial temperature grade available (對比EPM3064ATC100-10 (commercial variant))

設計說明
The EPM3064ATI100-10 requires a single 3.3 V supply for both VCCINT and VCCIO. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed as close as possible to the package, plus a bulk 10 uF tantalum or ceramic capacitor near the device. Estimated: ICC at 64 macrocells switching simultaneously may reach 50-100 mA; design the 3.3 V rail for at least 200 mA peak to allow margin during in-system programming.
The 100-pin TQFP package has a 0.5 mm lead pitch, requiring careful PCB layout. Use 4-mil traces and 8-mil spaces between pins, with vias placed outside the package footprint. Provide a solid ground plane beneath the device for noise suppression and thermal dissipation. Keep JTAG signals (TCK, TMS, TDI, TDO) routed away from high-speed switching traces to prevent programming interference.
The MAX 3000A I/Os support PCI-compatible signaling in the -4 through -10 grades but are not 5 V tolerant. When interfacing to 5 V logic, insert series resistors (100-470 ohm) on outputs or use external level-shifters. Configure slew-rate control for outputs driving long traces or bus topologies to reduce EMI and ground bounce. Verify setup/hold margins against the 10 ns pin-to-pin delay budget for your slowest paths.
Do not confuse the EPM3064ATI100-10 with the MAX 7000A family - they use different programming files and JTAG IDs. The MAX 3000A is obsolete; for new designs consider migrating to the MAX II family (EPM240T100) which offers more logic density and active lifecycle support. When substituting the EPM7064AETI100-7N, recompile the design and re-validate pin assignments against the MAX 7000A datasheet, as some dedicated pins differ between families.
