Product details
Overview
AT17LV010-10CI from Atmel is a 1-Mbit (1,048,576 × 1-bit) low-voltage FPGA configuration EEPROM designed for serial loading of SRAM-based FPGAs including Xilinx Virtex™, Spartan®, XC4000™, Altera APEX™ and FLEX®, Lucent ORCA®, and Atmel AT40K/AT94K devices. It operates at 3.3V ±10%, supports in-system programming via 2-wire bus, and features programmable reset polarity and system-friendly READY pin.
For engineers reviewing the AT17LV010-10CI datasheet, AT17LV010-10CI pinout, AT17LV010-10CI application, or AT17LV010-10CI equivalent, key selection criteria include 3.3V operation, industrial temperature range (–40°C to +85°C), cascading capability via CEO output, standby current ≤100 µA, and compatibility with Master Serial Mode FPGA configuration protocols.
Technical Context
The AT17LV010-10CI implements a serial-access EEPROM architecture optimized for FPGA configuration: it uses an internal address counter driven by CLK, tri-state DATA output controlled by CE and RESET/OE, and CEO output for daisy-chain cascading. Its SER_EN pin enables 2-wire ISP mode when pulled low, while remaining tied to VCC during normal FPGA boot.
It integrates EEPROM cell matrix with row/column decoding, bit counter, oscillator, and programming logic - all operating without external voltage pumps. The device supports write protection via WP1/WP2 inputs (disabled by default), programmable reset polarity, and power-on reset with READY pin assertion (open-collector, requires 4.7 kΩ pull-up).

FAQ
What is the primary function of the AT17LV010-10CI in an FPGA-based system?
The AT17LV010-10CI serves as a dedicated serial configuration memory that stores and delivers the bitstream required to initialize SRAM-based FPGAs such as Xilinx Virtex™ and Altera APEX™ devices. During power-up, the FPGA drives CLK and reads configuration data from the AT17LV010-10CI's DATA pin in Master Serial Mode - eliminating need for external controllers. Its CEO output enables chaining multiple AT17LV010-10CI units for larger bitstreams.
Does the AT17LV010-10CI support in-system programming, and how is it enabled?
Yes, the AT17LV010-10CI supports in-system programming (ISP) via a 2-wire serial interface. ISP is activated by pulling the SER_EN pin Low - this places the device into programming mode, allowing reprogramming of its EEPROM contents using industry-standard programmers or Atmel's ATDH2225 ISP Cable. During normal FPGA operation, SER_EN must be tied to VCC to ensure proper configuration sequencing.
Can the AT17LV010-10CI replace older 5V AT17C-series devices on the same PCB?
The AT17LV010-10CI is pin-compatible with AT17C010 variants in the same 8-lead LAP package and shares identical pin functions (including CEO, READY, SER_EN, and RESET/OE). However, it operates at 3.3V only and is not 5V-tolerant. Direct replacement requires confirming the host FPGA's I/O voltage is 3.3V and adjusting VCC supply - no PCB layout change is needed, but voltage domain validation is essential before substitution.
What is the role of the READY pin on the AT17LV010-10CI, and how should it be used?
The READY pin on the AT17LV010-10CI is an open-collector output that is actively driven Low during power-on reset and released (tri-stated) once internal circuitry stabilizes - indicating valid VCC and readiness to begin configuration. It must be externally pulled up with a 4.7 kΩ resistor. This signal can synchronize FPGA startup or drive system reset logic, ensuring configuration begins only after stable power conditions are met.
How does cascading work with multiple AT17LV010-10CI devices, and what is the timing impact?
Cascading uses the CEO (Chip Enable Output) pin of one AT17LV010-10CI to drive the CE input of the next device. When the first device reaches its final address, CEO goes Low, enabling the second device's DATA output. AC timing specifications confirm cascaded operation supports up to 12.5 MHz clock frequency - a 2.5 MHz reduction versus standalone mode - due to added propagation delay through CEO-to-CE path, as verified in the AT17LV010-10CI datasheet's cascading AC table.
