EP4CE15F17I7N

The EP4CE15F17I7N is an industrial-grade FPGA from Altera’s Cyclone IV E family — the fourth generation of Cyclone low-cost FPGAs, specifically engineered to deliver the lowest possible cost and power consumption for high-volume applications. Manufactured on TSMC’s 60nm low-power process technology with core options of 1.0V (for lowest power) or 1.2V (for highest performance), Cyclone IV E devices set a benchmark for low static power consumption while still providing substantial logic, memory, and DSP resources. The EP4CE15 variant provides 15,408 logic elements — a medium-sized configuration that balances resource availability with cost efficiency for a wide range of applications. The ‘F17’ indicates a 256-pin FineLine BGA package with 17mm body size, and ‘I7N’ denotes industrial temperature range (-40°C to +100°C junction temperature) with -7 speed grade. The logic architecture is built on refined logic elements containing 4-input look-up tables and programmable registers, organized into 963 logic array blocks (LABs) of 16 LEs each. The memory subsystem includes 56 M9K RAM blocks, each 9,216 bits, totaling 516 Kbits of on-chip memory configurable as single-port, dual-port, FIFO, shift register, or ROM. For digital signal processing, 56 embedded 18×18-bit multipliers provide dedicated hardware multiplication resources for efficient implementation of FIR filters, FFTs, and other DSP functions. Four phase-locked loops (PLLs) offer flexible clock synthesis with frequency multiplication/division, phase shifting, and spread-spectrum clocking capabilities. Twenty global clock networks provide robust, low-skew clock distribution across the device. The 256-pin FBGA package offers up to 181 user I/O pins organized into multiple independent I/O banks, supporting a comprehensive set of single-ended and differential I/O standards including LVDS at up to 805 Mbps. External memory interfaces support DDR2 SDRAM at up to 167 MHz (333 Mbps), as well as DDR and SDR SDRAM. The Cyclone IV E family is fully supported by Altera’s Quartus II design software and the extensive library of Altera IP cores including the Nios II soft embedded processor, DDR memory controllers, Ethernet MACs, and numerous DSP and interface functions. With its combination of low cost, low power, industrial temperature rating, and balanced resources, the EP4CE15F17I7N is ideal for cost-sensitive industrial, automotive, consumer, and communications applications.

The Cyclone IV E FPGA is an SRAM-based programmable logic device whose internal configuration is determined by data stored in static memory cells throughout the device. At power-up, the FPGA has no defined functionality — it must be configured by loading a bitstream that programs the logic elements, routing resources, I/O buffers, and memory blocks. Configuration can occur through several modes: Active Serial (AS) mode where the FPGA reads configuration data from an external serial flash device (EPCS or EPCQ series); Active Parallel (AP) mode for parallel Flash memory; Passive Serial (PS) or Fast Passive Parallel (FPP) mode where an external controller provides configuration data; or via the JTAG interface for in-system programming and debugging. The logic core is built from logic elements (LEs), each containing a 4-input look-up table (LUT) that can implement any Boolean function of up to 4 variables, plus a programmable flip-flop that can be configured as D, T, JK, or SR flip-flop for sequential logic. Carry chains enable efficient implementation of arithmetic functions like adders and counters. LEs are grouped into sets of 16 called logic array blocks (LABs), with each LAB having dedicated local interconnect for fast intra-LAB communication. The M9K memory blocks are 9,216-bit true dual-port SRAM blocks with various configuration options: single-port RAM, simple dual-port RAM, true dual-port RAM, shift register (RAM-based), ROM (with initialization data), or FIFO buffer (with almost-full/empty flags). Each embedded multiplier block contains an 18×18-bit multiplier that supports both signed and unsigned operations. These blocks can also be divided into two independent 9×9 multipliers for lower-precision applications, effectively doubling the multiplier count for DSP designs that don’t need full 18-bit precision. The four PLLs provide advanced clock synthesis including frequency multiplication and division, phase shifting with fine resolution, spread-spectrum clocking for electromagnetic interference (EMI) reduction, and clock switchover for clock redundancy applications. Twenty global clock networks with clock control blocks at the center of the device distribute clock signals with minimal skew to all regions of the FPGA. The I/O elements (IOEs) at the periphery provide configurable input/output buffers with support for many I/O standards, programmable drive strength, slew rate control, bus-hold, and pull-up/down resistors. Differential I/O buffers support LVDS and other differential standards for high-speed serial data transfer. The overall architecture provides a flexible fabric that can implement virtually any digital logic function — from simple state machines to complete systems-on-chip with Nios II processors, memory interfaces, and custom hardware accelerators.

The EP4CE15F17I7N is available in a 256-pin FineLine BGA package (17mm × 17mm body size). Major pin groups:

Note: Exact I/O count depends on power/ground pin count and dedicated function pins. Refer to the official Cyclone IV E EP4CE15 datasheet, Quartus II pin planner, and device pin files for complete pin assignments, I/O bank voltage assignments, and electrical specifications.
