Product details
Overview
AT17LV512-10CU from Microchip Technology (formerly Atmel) is a 512-kbit FPGA configuration EEPROM designed to store and serially load bitstream data into SRAM-based FPGAs during power-up. It supports dual-voltage operation (3.0–5.5 V), features programmable reset polarity, in-system programmability via 2-wire bus, and cascading capability via CEO output for multi-FPGA or high-density configurations. Used in industrial embedded systems requiring reliable, low-power nonvolatile configuration storage.
For engineers reviewing the AT17LV512-10CU datasheet, AT17LV512-10CU pinout, AT17LV512-10CU application, or AT17LV512-10CU equivalent, key selection considerations include its 8-lead LAP package compatibility with SOIC footprints, 10 MHz max clock frequency at 3.3 V, 524,288 × 1-bit organization, standby current of 100 µA, and support for Xilinx, Altera, and Atmel FPGA families.
Technical Context
The AT17LV512-10CU operates in Master Serial mode, interfacing directly with FPGA CCLK and DIN pins using simple synchronous serial protocol. Its internal address counter advances on CLK rising edge, and DATA output is open-collector with tri-state control via CE and RESET/OE.
It implements cascading through CEO - an active-low output that enables the next device's CE when the current device completes readout. The SER_EN pin selects between FPGA loading (high) and 2-wire ISP programming (low), with internal charge-pump programming voltage generation eliminating external high-voltage sources.
Key Specifications

Pinout & Package
AT17LV512-10CU is housed in an 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1.04 mm body, pin-compatible with standard 8-lead SOIC footprints. Features exposed thermal pad for improved heat dissipation in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | Three-state bidirectional I/O | Open-collector output during FPGA loading; used for serial data transfer and ISP programming |
| CLK | Input | Drives internal address/bit counter; synchronized to FPGA CCLK for deterministic timing |
| WP1 | Input | Secondary write protect; disabled by internal pull-down; prevents accidental overwrite of protected blocks |
| RESET/OE | Input/Output enable | Programmable polarity reset signal; also enables DATA output driver when CE is low |
| CE | Input | Chip enable (active low); disables counters and forces standby mode when high |
| GND | Power reference | Ground return path; requires 0.2 µF decoupling capacitor near VCC pin |
| CEO | Output | Cascade enable output (active low); triggers next EEPROM in daisy-chain after last bit read |
| SER_EN | Input | Selects operational mode: high = FPGA configuration mode; low = 2-wire ISP programming mode |
| VCC | Power supply | 3.0–5.5 V supply input; powers EEPROM core and interface logic |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability (ISP) | Enables field firmware updates via 2-wire serial interface without removing device from PCB |
| Cascadable CEO output | Allows daisy-chaining multiple AT17LV devices to support larger FPGA configurations or multi-FPGA boards |
| Programmable reset polarity | Supports both active-high and active-low reset configurations to match target FPGA requirements |
| Dual-voltage compatibility | Operates across 3.0–5.5 V range - eliminates need for separate voltage rails in mixed-signal FPGA systems |
| Low-power standby mode | Consumes only 100 µA at 3.3 V when CE is high - critical for battery-backed or energy-sensitive applications |

FAQ
What is the memory organization of the AT17LV512-10CU?
The AT17LV512-10CU contains a 524,288 × 1-bit (512 kbit) EEPROM array organized as a single linear address space. This structure supports sequential bitstream loading into SRAM-based FPGAs such as Xilinx Spartan and Virtex families, with each bit mapped directly to FPGA configuration cells during power-up or reset-initiated reload. The AT17LV512-10CU does not support byte-wide access or random addressing - it operates exclusively in serial streaming mode.
Can the AT17LV512-10CU be used with 5 V FPGAs?
Yes, the AT17LV512-10CU supports 3.0–5.5 V operation and is fully compatible with 5 V FPGAs including Xilinx XC4000 and Altera FLEX 10K families. Its VIH threshold is 2.0 V minimum and VOL is ≤0.4 V at 3 mA, ensuring clean logic-level interoperability. When used with 5 V systems, the AT17LV512-10CU achieves up to 15 MHz maximum clock frequency and consumes ≤200 µA in standby mode - verified per Table 10-6 in the official datasheet.
Does the AT17LV512-10CU support daisy-chaining with other configuration EEPROMs?
Yes, the AT17LV512-10CU includes a dedicated CEO (Chip Enable Output) pin that asserts low upon completion of its entire memory readout. This signal can directly drive the CE input of a second AT17LV device in a cascaded chain, enabling seamless expansion beyond 512 kbit. Cascading is supported across all package variants and requires no additional logic - the AT17LV512-10CU handles handoff timing internally, as confirmed in Section 6 and Figure 10-2 of the datasheet.
What programming interfaces does the AT17LV512-10CU support?
The AT17LV512-10CU supports two distinct programming modes: (1) Standard FPGA configuration mode, where SER_EN is tied high and the device streams data synchronously to the FPGA's CCLK; and (2) In-system programming (ISP) mode, activated by pulling SER_EN low to enable 2-wire serial interface compatible with industry-standard programmers like the Atmel ATDH2225 ISP Cable. No external high-voltage programming supply is needed - internal charge pumps generate required voltages.
Is the AT17LV512-10CU pin-compatible with other AT17LV family members?
The AT17LV512-10CU shares identical pinout and functionality with AT17LV010-10CU and AT17LV002-10CU in the 8-lead LAP (8CN4) package, enabling direct density upgrades without PCB changes. However, it is not pin-compatible with older AT17LV65/128/256 devices due to differences in WP and CEO pin assignments - Table 1-2 and Note 2 in the datasheet explicitly confirm this incompatibility for NRND parts.
