5M2210ZF256C4N - MAX V CPLD, 1700 LE, FBGA-256, C4 Speed | Intel / Altera
MPN: 5M2210ZF256C4N ✓ Hoạt động5M2210ZF256C4N Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs/GALs and higher-density FPGAs in the programmable logic hierarchy (CPLD -> PLD -> programmable logic -> digital IC). MAX V CPLDs are built on a 0.30 um 6-metal-layer CMOS process with a flash-based configuration cell, providing instant-on operation in less than 1 ms without an external boot PROM. They are used as glue logic, I/O expansion, interface bridging, and power-sequencing controllers in industrial, communications, and consumer systems. Unlike SRAM-based FPGAs that require external configuration memory, MAX V devices self-configure at power-up from internal flash.
Key features of the 5M2210ZF256C4N include 1700 LEs arranged in 221 Logic Array Blocks (LABs), 160 user I/O pins available in this FBGA-256 outline, a 1.8 V core supply (VCCINT) with multi-voltage I/O bank support (1.5 V, 1.8 V, 2.5 V, 3.3 V LVCMOS/LVTTL), and an internal oscillator plus JTAG (IEEE 1149.1) and IEEE 1532 in-system programmability. Typical tPD pin-to-pin delay is in the 4 ns class for speed grade 4, suitable for control-path rather than high-speed datapath applications. The device supports live insertion and 5 V tolerant I/O when the bank VCCIO is set below 3.3 V.
The device integrates the JTAG controller, internal voltage regulator, and configuration flash memory on-die, eliminating the external programming PROM required by legacy MAX and MAX II CPLDs. It also provides four user I/O banks for flexible mixed-voltage interfacing, allowing direct connection to 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic without external level shifters.
Typical applications include bus interface bridging (e.g. PCI to local bus), I/O expansion for microcontrollers and ASICs, power-supply sequencing in multi-rail systems, configuration/control for companion FPGAs, and glue logic in industrial controllers and consumer set-top boxes. The FBGA-256 package and high I/O count make it suitable for high-density board-level integration.
When designing with this part, route all four VCCIO bank supplies and at least one VCCINT (1.8 V) supply with adequate decoupling (0.1 uF + bulk); unused I/O pins should be left floating or driven to a defined logic level to minimize in-rush during power-up. The 256-ball FBGA requires X-ray or BGA rework equipment for prototype bring-up, so allocate 2-3 days for first-article assembly.

Ứng dụng tiêu biểu
5M2210ZF256C4N phù hợp cho 6 Áp dụngs: Multi-Rail Power Supply Sequencing, Bus Interface Bridging (PCI / Local Bus), Microcontroller I/O Expansion, FPGA Configuration & Control Companion, Industrial Glue Logic & Protocol Conversion, Consumer Set-Top Box & Home Gateway Logic.
Multi-Rail Power Supply Sequencing
The 5M2210ZF256C4N's four independent VCCIO banks, instant-on flash configuration, and 160 user I/O pins make it an ideal power-supply sequencing controller for multi-rail systems. Each of the four VCCIO banks can be powered at 1.5 V, 1.8 V, 2.5 V, or 3.3 V, allowing direct logic-level interface to enable pins of DC-DC converters and LDOs without external level shifters. The MAX V internal flash eliminates the boot PROM required by older MAX II designs, simplifying the BOM. The 5M2210ZF256C4N's typical tPD of ~4 ns (C4 speed grade) is more than adequate for sequenced enable signals in the millisecond regime, while the 1.8 V VCCINT core minimizes quiescent power. Compared to discrete sequencer ICs, this CPLD adds flexibility to reprogram turn-on/off order via JTAG without PCB rework.
Được đề xuất
Bus Interface Bridging (PCI / Local Bus)
The 5M2210ZF256C4N provides 160 user I/O and 1700 Logic Elements, sufficient to bridge legacy 32-bit PCI buses to local processor buses in industrial and embedded designs. Its 3.3 V VCCIO bank support directly interfaces 5 V tolerant I/O when the bank is biased below 3.3 V, eliminating external level shifters. The 5M2210ZF256C4N's 4 ns tPD (C4 speed grade) comfortably meets PCI 33 MHz bus timing with adequate margin for address decode and wait-state insertion. The internal flash configuration enables in-field firmware updates via JTAG, useful for fixing bus-timing bugs without board replacement. Compared to discrete glue-logic ICs, this CPLD consolidates 5-10 TTL packages into a single BGA, saving PCB area and BOM cost.
Được đề xuất
Microcontroller I/O Expansion
The 5M2210ZF256C4N expands I/O capacity for microcontrollers and ASICs that lack sufficient pins, exposing up to 160 user I/O and connecting via SPI, I2C, or parallel sideband interfaces. The 1.8 V VCCINT core plus four VCCIO banks support modern SoCs running at 1.8 V while driving 3.3 V peripherals in the same design. The 5M2210ZF256C4N's flash-based instant-on (<1 ms) configuration avoids the boot latency of SRAM-based FPGA expansion solutions. With 1700 LEs, it can implement shift registers, PWM generators, encoder/decoders, and custom serial protocols in addition to raw I/O expansion. The FBGA-256 package suits space-constrained designs where 160 I/O are needed in a small footprint.
Được đề xuất
FPGA Configuration & Control Companion
The 5M2210ZF256C4N serves as a low-cost configuration and control companion to higher-density SRAM-based FPGAs such as Altera Cyclone V or Xilinx Artix-7 in the same system. Its flash-based instant-on operation (<1 ms) can hold the main FPGA in reset, generate proper power-good signals, and sequence supply rails before releasing the FPGA reset pin. The 160 user I/O of the 5M2210ZF256C4N provide ample bandwidth for SPI/parallel configuration loading, status monitoring, and sideband control signals. Compared to a discrete CPLD+FPGA architecture with separate boot PROMs, the MAX V flash integrates the configuration memory on-die, reducing BOM and board area.
Được đề xuất
Industrial Glue Logic & Protocol Conversion
The 5M2210ZF256C4N consolidates 5-10 discrete 74-series TTL/CMOS glue-logic packages into a single FBGA-256 device, simplifying PCB layout in industrial controllers, motor drives, and PLCs. With 1700 LEs, it can implement UART, SPI, I2C, parallel-to-serial conversion, encoder interfaces, and watchdog timers in a single chip. The commercial 0C to 85C operating range suits most indoor industrial enclosures, while the 5M2210ZF256I5N variant extends to industrial -40C to 100C for outdoor/harsh environments. The 4 VCCIO banks enable direct interface to 1.8 V SoCs, 2.5 V DSPs, 3.3 V sensors, and 5 V tolerant legacy signals within the same design.
Được đề xuất
Consumer Set-Top Box & Home Gateway Logic
The 5M2210ZF256C4N delivers cost-optimized glue logic, I/O expansion, and LED-driving capability for consumer set-top boxes, home gateways, and smart-home hubs. Its 160 user I/O drive front-panel buttons, LED status indicators, IR receivers, and HDMI CEC sideband signals without external mux ICs. The flash-based instant-on (<1 ms) configuration avoids visible boot delays for always-on consumer devices. Compared to MCUs in similar roles, the 5M2210ZF256C4N offers deterministic pin-to-pin logic with no firmware interrupt latency, ideal for real-time LED multiplexing and IR decoding. The FBGA-256 footprint suits compact consumer electronics form factors.

Ghi chú thiết kế
Estimated: at typical 1.8 V VCCINT plus four 3.3 V VCCIO banks each supplying ~20 mA of I/O current, the 5M2210ZF256C4N consumes approximately 50-150 mA quiescent current (depending on logic utilization). Per the Intel MAX V family datasheet, decouple each VCCINT ball with a 0.1 uF ceramic capacitor placed within 5 mm of the ball, and add one bulk 10 uF tantalum or ceramic capacitor per VCCIO bank. Sequence VCCINT before VCCIO to prevent I/O latch-up during power-up.
The FBGA-256 package has a 17x17 ball grid at 1.0 mm pitch and requires 4-6 layer PCB with microvia stackups (any-layer HDI preferred for breakout). Per the Intel MAX V hardware design guide, route all VCCINT and VCCIO traces with at least 0.2 mm width, use a continuous ground plane on layer 2 directly beneath the BGA, and provide at least 4 ground balls per VCCIO bank to minimize ground bounce. BGA assembly requires X-ray inspection; do not attempt hand-rework.
Avoid leaving unused user I/O pins floating - per the Intel MAX V datasheet, configure them as outputs driving a defined logic level or as outputs driving low to minimize in-rush current during power-up. Do not exceed the maximum VCCIO-to-VCCINT voltage differential of 2.5 V during hot-plug events. Always program the JTAG IDCODE register before relying on JTAG chain integrity checks.
