EPC2TI32 - 1.6Mb In-System Prog Config PROM | Altera (Intel)
MPN: EPC2TI32 ✗ Cuối đờiEPC2TI32 Tóm tắt
A configuration PROM is a non-volatile serial memory that holds the FPGA's configuration bitstream. When the system powers up or when a reconfiguration is requested, the FPGA's controller reads the bitstream serially from the PROM through dedicated configuration pins (DATA, DCLK, nCONFIG, nSTATUS, CONF_DONE). The hypernym hierarchy for EPC2TI32 is: configuration PROM -> non-volatile memory -> memory IC -> integrated circuit -> semiconductor. Configuration PROMs replaced legacy EPROM-based configuration methods by eliminating the need for external programmers and enabling on-board upgrades via JTAG.
Key features of the EPC2TI32 include 1.6 Mbit (2 Mbit logical, 1.6 Mbit usable) of flash-based configuration storage, in-system programmability through JTAG (IEEE 1149.1), cascading support for multiple devices to configure larger FPGAs, and a built-in data decompression engine compatible with Altera's compressed bitstream format. The 10 MHz DCLK supports typical configuration times of approximately 200 ms for an APEX 20K100 device. The 32-pin TQFP package is industry-standard and supports conventional SMT assembly.
Typical applications include APEX II / APEX 20K / FLEX 10K / ACEX 1K / Cyclone FPGA configuration memory, single-FPGA and multi-FPGA cascading configurations, industrial control boards requiring in-field firmware updates, telecom line cards with remote bitstream updates, and prototyping platforms that require rapid bitstream iteration via JTAG. The wide operating voltage range (3.0 V to 5.5 V) makes the EPC2TI32 suitable for legacy 5 V systems as well as modern 3.3 V designs.
When designing with the EPC2TI32, ensure that the JTAG chain order matches the silicon revision of your target FPGA, and that the CONF_DONE pull-up resistor is sized correctly per the Altera application note AN-123. For modern Cyclone IV or later FPGAs, EPCS serial configuration devices are typically preferred, but EPC2TI32 remains a robust choice for legacy 5 V APEX/FLEX systems.

Ứng dụng tiêu biểu
EPC2TI32 phù hợp cho 6 Áp dụngs: APEX 20K Series FPGA Configuration, FLEX 10K FPGA Configuration Memory, Cyclone FPGA Configuration (Original Series), Industrial Control Boards with Field Updates, Telecom Line Cards with Remote Bitstream Updates, Prototyping Platforms and Development Kits.
APEX 20K Series FPGA Configuration
The EPC2TI32 stores the configuration bitstream for Altera APEX 20K series FPGAs (APEX 20K100, 20K200, 20K400). The 1.6 Mbit density is sufficient for APEX 20K100 bitstreams; for larger APEX 20K devices, multiple EPC2TI32s can be cascaded. The 10 MHz DCLK delivers typical configuration times of about 200 ms, and the 5 V supply range matches APEX 20K's core voltage requirement.

FLEX 10K FPGA Configuration Memory
The EPC2TI32 is designed as the configuration PROM for Altera FLEX 10K series FPGAs (FLEX 10K10, 10K30, 10K50, 10K100, 10K130). Its 1.6 Mbit density is well-matched to FLEX 10K30 / 10K50 bitstreams, and the JTAG ISP interface enables field firmware updates without removing the board. The 3.3 V or 5 V supply supports both legacy and modern FLEX 10K designs.
Được đề xuất
Cyclone FPGA Configuration (Original Series)
The EPC2TI32 configures the original Altera Cyclone (EP1C3, EP1C6, EP1C12, EP1C20) FPGAs. The 1.6 Mbit density is sufficient for EP1C3 / EP1C6 bitstreams, and the serial configuration protocol at 10 MHz matches Cyclone's CONFIG_MODE serial interface. Note: Cyclone II and later require EPCS configuration devices, not EPC2.
Được đề xuất
Industrial Control Boards with Field Updates
The EPC2TI32's JTAG ISP interface enables in-field configuration updates via standard JTAG probe tools (ByteBlasterMV, USB-Blaster). Industrial control systems with deployed PLC or motion-controller FPGAs benefit from this field-programmability for bug fixes and feature updates. The -40C to +85C industrial temperature range supports factory floor environments.
Được đề xuất
Telecom Line Cards with Remote Bitstream Updates
The EPC2TI32's JTAG ISP and 1.6 Mbit density make it suitable for telecom line cards built on Altera FPGAs. Combined with a JTAG-over-Ethernet controller, the bitstream can be updated remotely for protocol changes, security patches, or feature rollouts. The 32-TQFP package supports standard SMT assembly on telecom-grade PCBs.
Được đề xuất
Prototyping Platforms and Development Kits
The EPC2TI32's JTAG ISP and Altera protocol support make it a workhorse on APEX/FLEX/ACEX development boards. Engineers can iterate bitstreams in seconds via JTAG without removing the PROM. The 32-TQFP package is breadboard-compatible and integrates cleanly with standard FPGA development kits.

Ghi chú thiết kế
The EPC2TI32 operates from a single 3.0 V to 5.5 V supply. Decouple VCC pins (1, 10, 11, 26, 27, 30, 31) with 100 nF ceramic capacitors placed within 5 mm of each pin group, plus a bulk 10 uF tantalum or ceramic capacitor on the main supply rail. During in-system programming, peak current can momentarily increase; ensure the regulator has at least 50 mA of headroom above the steady-state active current.
A common pitfall is attempting to use the EPC2TI32 with Cyclone II or newer FPGAs. Cyclone II and later devices require EPCS (EPCS1, EPCS4, EPCS16, EPCS64) configuration devices because they use the enhanced serial configuration protocol. The EPC2TI32 is limited to APEX II, APEX 20K, Mercury, FLEX 10K, ACEX 1K, and original Cyclone families. Using an EPC2 with a Cyclone II will result in configuration failure.
Place the EPC2TI32 close to the target FPGA to minimize trace length on the serial DATA and DCLK lines. Keep DCLK trace length below 50 mm and route it away from switching power lines to avoid coupling noise into the configuration data stream. For JTAG chains, the EPC2TI32 should be placed in series with the FPGA in the JTAG chain, with TCK/TMS buffered if chain length exceeds 150 mm.
