Product details
Overview
AT17LV512-10CC from Microchip Technology (formerly Atmel) is a 512-Kbit serial FPGA configuration EEPROM designed to store and load bitstream programs for SRAM-based FPGAs in master serial mode. It supports dual-voltage operation (3.3V ±10% or 5.0V ±5%/±10%), features cascading CEO output, programmable reset polarity, and operates across commercial temperature range (0°C to +70°C). Its primary role is nonvolatile configuration memory interfacing directly with Xilinx XC3000/XC4000/Spartan, Altera FLEX/APEX, and Atmel AT40K/AT94K FPGAs.
For engineers reviewing the AT17LV512-10CC datasheet, AT17LV512-10CC pinout, AT17LV512-10CC application, or AT17LV512-10CC equivalent, key selection criteria include its 8-lead LAP package compatibility with SOIC footprints, 15 MHz max clock frequency at 5V, cascaded daisy-chain capability via CEO, low-power standby current (100 µA industrial, 200 µA commercial), and EEPROM endurance of 100,000 write cycles with 90-year data retention at 85°C.
Technical Context
The AT17LV512-10CC implements a serial-access configuration memory architecture synchronized to FPGA CCLK, using CE, RESET/OE, and SER_EN control signals to manage address counter enablement, output tri-state behavior, and ISP entry. Its internal logic supports both active-low RESET and active-high OE modes, configurable via EEPROM programming.
It integrates dedicated pins for cascading (CEO), two-wire ISP programming (SER_EN, A2), and write protection (WP1, WP2), with distinct pin mappings between the AT17LV512/010/002 family and earlier AT17LV65/128/256 variants - notably excluding WP and including CEO and READY only on higher-density members.

FAQ
What is the maximum clock frequency supported by the AT17LV512-10CC during FPGA configuration?
The AT17LV512-10CC supports a maximum clock frequency of 15 MHz when operating at 5.0V (commercial grade). At 3.3V, the max frequency is 10 MHz. These values are specified under AC characteristics tables and reflect guaranteed timing margins for reliable data output synchronization with FPGA CCLK. The AT17LV512-10CC must meet these limits to ensure correct bitstream delivery without setup/hold violations.
Does the AT17LV512-10CC support in-system programming (ISP), and what interface is required?
Yes, the AT17LV512-10CC supports in-system programming via a two-wire serial interface. This requires pulling the SER_EN pin low and using the DATA and CLK pins as bidirectional SDA/SCL lines. Programming is performed at the same VCC supply voltage (3.3V or 5.0V) - no external high-voltage programming signal is needed, as internal charge pumps generate required programming voltages. The AT17LV512-10CC retains full ISP capability in-circuit.
Can the AT17LV512-10CC be used in a daisy-chain configuration with other AT17LV devices?
Yes, the AT17LV512-10CC includes a CEO (Chip Enable Output) pin that asserts low upon reaching the final memory address, enabling automatic handoff to the next device in a daisy chain. This feature is explicitly supported for cascading with other AT17LV512/010/002/040 devices. Note that AT17LV65/128/256 devices lack CEO and are not compatible in such chains. The AT17LV512-10CC's CEO pin ensures seamless multi-device configuration without external logic.
What is the purpose of the RESET/OE pin on the AT17LV512-10CC, and how is its polarity configured?
The RESET/OE pin on the AT17LV512-10CC serves dual functions: active-low RESET (to reset the internal address counter) and active-high OE (to enable the DATA output driver). Its logic polarity is user-programmable via four EEPROM bytes - allowing configuration as either RESET/OE or RESET/OE to match specific FPGA requirements. This programmability is implemented in the AT17LV512-10CC's nonvolatile memory and persists across power cycles.
Is the AT17LV512-10CC pin-compatible with standard 8-lead SOIC packages?
Yes, the AT17LV512-10CC is offered in an 8-lead Leadless Array Package (LAP) with identical 6 mm × 6 mm footprint and 1.27 mm pitch as JEDEC-standard 8-lead SOIC. Though physically distinct (no gull-wing leads), the LAP package is explicitly designed for SOIC-compatible PCB layouts - enabling direct substitution without board revision. This compatibility is confirmed in Atmel documentation and reflected in the AT17LV512-10CC ordering code suffix "CC" (Commercial, LAP).
