Product details
Overview
AT17LV010-10CC from Atmel is a 1-Mbit (1,048,576 × 1-bit) low-voltage serial EEPROM FPGA configuration memory, designed to store and load bitstream data for SRAM-based FPGAs including Xilinx Spartan®, Virtex™, Altera FLEX®, and Lattice ORCA® devices. It operates at 3.3V ±10%, supports in-system programming via 2-wire bus, features programmable reset polarity, and includes a system-friendly READY pin for power-up sequencing.
For engineers reviewing the AT17LV010-10CC datasheet, AT17LV010-10CC pinout, AT17LV010-10CC application, or AT17LV010-10CC equivalent, key selection criteria include 3.3V operation, cascading capability via CEO/CE daisy-chain, standby current ≤100 µA, and compatibility with Master Serial Mode FPGA configuration protocols.
Technical Context
The AT17LV010-10CC implements a serial-access architecture synchronized to an external FPGA-provided CLK signal, with internal address counter and bit counter controlled by CE, RESET/OE, and SER_EN. Its EEPROM cell matrix uses low-power CMOS process and supports write protection via WP1/WP2 inputs.
It operates in two distinct modes: FPGA loading mode (SER_EN = High), where DATA output drives FPGA DIN, and ISP programming mode (SER_EN = Low), enabling 2-wire serial programming without external high-voltage sources. CEO output enables daisy-chained configuration of multiple FPGAs or higher-density arrays.
Key Specifications

|---|---|
| Memory size | 1,048,576 × 1-bit (1 Mbit) nonvolatile EEPROM storage for full FPGA configuration bitstreams |
| Supply voltage | 3.3 V ±10% - compatible with modern low-voltage FPGA I/O domains and reduces system power overhead |
| Max clock frequency | 15 MHz (standalone), 12.5 MHz (cascaded) - sets upper bound on configuration speed for single or chained devices |
| Standby current | ≤100 µA at 3.3V - enables ultra-low-power retention during FPGA idle or sleep states |
| Operating temperature | 0°C to +70°C (Commercial) - validated for industrial control panels and communications equipment enclosures |

Pinout & Package
AT17LV010-10CC is packaged in an 8-lead Leadless Array Package (LAP), 6 mm × 6 mm × 1 mm body, pin-compatible with 8-lead SOIC/VOIC footprints. This surface-mount package supports high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DATA) | Bi-directional I/O | Three-state open-collector output during read; bidirectional shift register I/O during ISP programming |
| 2 (CLK) | Input | Synchronizes internal address/bit counter; driven by FPGA CCLK in Master Serial Mode |

| 5 (VCC) | Power | +3.3V supply input; requires local 0.2 µF decoupling capacitor to GND per datasheet recommendation |
| 6 (SER_EN) | Input | Serial enable; must be tied to VCC for FPGA configuration; pulled low to enter 2-wire ISP programming mode |
| 7 (CEO) | Output | Active-Low chip enable output; signals end-of-data to next device in daisy-chain cascade |
| 8 (GND) | Ground | Reference ground plane connection; critical for noise immunity in high-speed serial configuration paths |
Key Features

| Programmable reset polarity | Four EEPROM bytes configure RESET/OE as active-Low or active-High, eliminating need for external inverters |
| System-ready signaling | READY pin asserts low during power-on reset and releases (tri-states) upon VCC stabilization - directly interfaces with FPGA PROG_B or INIT_B |
| Low-power standby mode | CE = High reduces ICCS to ≤100 µA, enabling energy-efficient configuration management in battery-backed or always-on systems |

FAQ
What is the primary function of the AT17LV010-10CC in an FPGA-based system?
The AT17LV010-10CC serves as a dedicated serial configuration memory that stores and delivers the FPGA bitstream during power-up or reconfiguration. It interfaces directly with SRAM-based FPGAs (e.g., Xilinx Spartan®, Virtex™, Altera FLEX®) in Master Serial Mode, using CLK, DATA, CE, and RESET/OE signals. The AT17LV010-10CC eliminates the need for external controllers by embedding address counting, output enable logic, and daisy-chain support - making it a self-contained, pin-optimized solution for FPGA configuration.
Does the AT17LV010-10CC support in-system programming (ISP), and how is it enabled?
Yes, the AT17LV010-10CC supports in-system programming via a 2-wire serial interface. ISP is enabled by driving the SER_EN pin low, which places the device into programming mode. In this mode, industry-standard programmers (e.g., Atmel ATDH2225 ISP Cable) can read, verify, and reprogram the EEPROM contents without removing the AT17LV010-10CC from the PCB. During normal FPGA operation, SER_EN must be tied to VCC to ensure proper configuration timing and signal integrity.
How does the CEO pin function in a cascaded configuration using multiple AT17LV010-10CC devices?
The CEO (Chip Enable Output) pin of the AT17LV010-10CC goes active-low when its internal address counter reaches the final memory location. In a daisy-chain setup, this CEO signal connects to the CE (Chip Enable) input of the next AT17LV010-10CC device, automatically enabling it to begin outputting its stored bitstream. This hardware-controlled handoff ensures seamless, glitch-free cascading without FPGA firmware intervention - a core feature distinguishing the AT17LV010-10CC from generic SPI EEPROMs.
Can the AT17LV010-10CC be used with 5V FPGAs, and what are the voltage compatibility constraints?
No, the AT17LV010-10CC is strictly a 3.3V device (3.0V–3.6V operation) and is not 5V-tolerant. Its I/O pins are designed for 3.3V logic levels and lack 5V input protection. Using it with 5V FPGAs risks damage or unreliable operation unless level-shifting circuitry is added. For 5V systems, the pin-compatible AT17C010-10CC (5V version) should be selected instead. Both share identical pinout and functionality but differ in supply voltage and AC timing specifications.
What is the role of the READY pin on the AT17LV010-10CC, and how should it be connected?
The READY pin is an open-collector output that is actively driven low during the AT17LV010-10CC's internal power-on reset cycle and tri-stated (released) once VCC stabilizes and the device is ready to respond to commands. It provides a hardware handshake to the FPGA (e.g., connected to PROG_B or INIT_B) to delay configuration start until power is valid. A 4.7 kΩ pull-up resistor to VCC is required on the READY line to ensure proper logic-high state when released - a mandatory design detail specified in the AT17LV010-10CC datasheet.
