EPM1270F256C5N Datasheet

CPLD - Complex Programmable Logic Devices


EPM1270F256C5N The MAX® II family of instant-on, non-volatile CPLDs is based on a 0.18-µm, 6-layer-metal-flash process, with densities from 240 to 2,210 logic elements (LEs) (128 to 2,210 equivalent macrocells) and non-volatile storage of 8 Kbits. MAX II devices offer high I/O counts, fast performance, and reliable fitting versus other CPLD architectures. Featuring MultiVolt core, a user flash memory (UFM) block, and enhanced in-system programmability (ISP), MAX II devices are designed to reduce cost and power while providing programmable solutions for applications such as bus bridging, I/O expansion, power-on reset (POR) and sequencing control, and device configuration control. EPM1270F256C5N Features • Low-cost, low-power CPLD • Instant-on, non-volatile architecture• Standby current as low as 25 µA• Provides fast propagation delay and clock-to-output times• Provides four global clocks with two clocks available per logic array block (LAB)• UFM block up to 8 Kbits for non-volatile storage• MultiVolt core enabling external supply voltages to the device of either 3.3 V/2.5 V or 1.8 V• MultiVolt I/O interface supporting 3.3-V, 2.5-V, 1.8-V, and 1.5-V logic levels• Bus-friendly architecture including programmable slew rate, drive strength, bus-hold, and programmable pull-up resistors• Schmitt triggers enabling noise tolerant inputs (programmable per pin)• I/Os are fully compliant with the Peripheral Component Interconnect Special Interest Group (PCI SIG) PCI Local Bus Specification, Revision 2.2 for 3.3-V operation at 66 MHz • Supports hot-socketing• Built-in Joint Test Action Group (JTAG) boundary-scan test (BST) circuitry compliant with IEEE Std. 1149.1-1990• ISP circuitry compliant with IEEE Std. 1532
