Product details
Overview
AT17LV512-10JC from Atmel is a 512-Kbit serial FPGA configuration EEPROM designed for master-serial mode loading of SRAM-based FPGAs. It supports dual-voltage operation (3.3V ±10% or 5.0V ±5%/±10%), offers programmable reset polarity, provides cascading via CEO output, and delivers 100,000 write cycles with 90-year data retention at 85°C (industrial grade).
For engineers reviewing the AT17LV512-10JC datasheet, AT17LV512-10JC pinout, AT17LV512-10JC application, or AT17LV512-10JC equivalent, key selection criteria include its 20-lead PLCC industrial-grade package, CEO-enabled daisy-chain capability, two-wire ISP support, low-power standby current (100 µA @ 3.3V), and compatibility with Xilinx XC4000/XC5200/Spartan, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
Technical Context
The AT17LV512-10JC implements a serial configuration memory architecture with synchronous clock-driven readout, where CLK increments an internal address counter and DATA outputs configuration bits to the FPGA's DIN pin. Its RESET/OE pin serves dual functions-active-Low reset and active-High output enable-with polarity programmable in EEPROM bytes.
Cascading relies on the CEO output: when one device completes transmission, CEO goes Low to enable the CE input of the next device in chain. The SER_EN pin selects between FPGA loading mode (SER_EN = High) and two-wire ISP programming mode (SER_EN = Low), with internal charge-pump generation eliminating external high-voltage requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Xilinx XC18V02 | 2-Mbit capacity; 20-lead PLCC; supports only 3.3V; no CEO output; no ISP capability | Limited to single-device configurations; requires external programmer; incompatible with daisy-chain topologies | Select when higher density is needed and cascading is unnecessary; verify FPGA compatibility with XC18V series timing |
| Microchip (Atmel) AT17LV010-10JC | 1-Mbit capacity; identical 20-lead PLCC package; same CEO, SER_EN, and dual-voltage support; 100,000 write cycles | Provides double the configuration storage for larger FPGAs (e.g., XC5200XL, Virtex-E); same industrial temperature range | Choose for future-proofing or migration path when FPGA bitstream size exceeds 512 Kbit; pin-compatible drop-in upgrade |
Compared with XC18V02 and AT17LV010-10JC, the AT17LV512-10JC uniquely balances mid-density storage (512 Kbit), industrial temperature operation, CEO-enabled cascading, and two-wire ISP - making it optimal for cost-sensitive, field-upgradable, multi-FPGA industrial systems where 1-Mbit is excessive and 2-Mbit lacks ISP.

FAQ
What is the primary function of the AT17LV512-10JC in an FPGA-based system?
The AT17LV512-10JC serves as a dedicated serial configuration memory that stores and delivers the bitstream required to initialize SRAM-based FPGAs such as Xilinx Spartan and Altera FLEX devices. During power-up or reset, it streams configuration data synchronously via the CLK and DATA lines to the FPGA's DIN pin in master-serial mode - enabling autonomous, repeatable, and reliable FPGA startup without external controllers. Its design directly supports industry-standard FPGA configuration protocols.
Does the AT17LV512-10JC support in-system programming (ISP), and how is it enabled?
Yes, the AT17LV512-10JC supports two-wire in-system programming via the SER_EN and DATA/CLK pins. To activate ISP mode, SER_EN must be driven Low while VCC is applied; this places the device into serial programming mode, allowing bitstream updates using standard industry programmers or custom firmware. The AT17LV512-10JC does not require external high-voltage supplies, as internal charge pumps generate necessary programming voltages - a key advantage over older parallel PROMs.
How does the CEO pin on the AT17LV512-10JC enable cascaded FPGA configurations?
The CEO (Chip Enable Output) pin on the AT17LV512-10JC goes Low when its internal address counter reaches the final memory location, signaling completion of data transmission. In a daisy chain, this CEO output connects directly to the CE (Chip Enable) input of the next AT17LV device, automatically enabling it to begin streaming its own bitstream. This hardware handshaking eliminates timing-critical software coordination and supports seamless expansion beyond 512 Kbit - a capability absent in smaller AT17LV variants like the AT17LV256.
What are the valid supply voltage ranges and operating temperature specifications for the AT17LV512-10JC?
The AT17LV512-10JC operates across two voltage domains: 3.3 V ±10% or 5.0 V ±5% (commercial grade, 0°C to +70°C) and 5.0 V ±10% (industrial grade, –40°C to +85°C). Its -10JC suffix explicitly denotes the industrial temperature range and 20-lead PLCC package. These dual-voltage and extended-temperature capabilities make the AT17LV512-10JC suitable for deployment in harsh environments such as factory automation, outdoor telecom nodes, and transportation control systems.
Can the AT17LV512-10JC be used with both Xilinx and Altera FPGAs, and what ensures compatibility?
Yes, the AT17LV512-10JC is explicitly qualified for use with Xilinx XC3000/XC4000/XC5200/Spartan/Virtex families and Altera FLEX/APEX devices, as confirmed in Atmel's official documentation. Compatibility is ensured by adherence to master-serial configuration timing parameters (e.g., TCAC ≤ 60 ns @ 3.3V industrial), pin-functional alignment (CLK → CCLK, DATA → DIN, RESET/OE → PROGRAM_B/INIT_B), and support for standard FPGA reset sequencing - including programmable reset polarity to match vendor-specific active-Low or active-High requirements without hardware modification.
