Product details

Overview

AT17LV002-10TQI from Microchip Technology (formerly Atmel) is a 2-Mbit serial EEPROM FPGA configuration memory, designed to store and load bitstreams into SRAM-based FPGAs via master serial mode. 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. Used in industrial-grade FPGA systems requiring reliable, nonvolatile configuration storage.

For engineers reviewing the AT17LV002-10TQI datasheet, AT17LV002-10TQI pinout, AT17LV002-10TQI application, or AT17LV002-10TQI equivalent, this page delivers verified technical context, package-specific pin mapping, real-world FPGA integration details, and validated alternative options - all grounded in the official AT17C/LV002 Rev. 2281D datasheet and Microchip's ordering documentation.

Technical Context

The AT17LV002-10TQI implements a serial-access EEPROM architecture optimized for FPGA configuration loading: it uses a synchronous clock-driven address counter, tri-state DATA output controlled by CE and RESET/OE, and cascading support via CEO output. Its SER_EN input enables 2-wire ISP mode while disabling FPGA loading when low.

It integrates internal voltage regulation for 3.3V operation, supports write protection via WP1, and provides programmable reset polarity (active-low RESET or active-high OE) stored in EEPROM. The READY pin delivers open-collector power-on reset status, and standby current is ≤200 µA with CE high.

18	CE	Chip Enable (active Low) - enables readout and address incrementing; forces standby mode when high.
23	GND	Ground reference - requires local 0.2 µF decoupling capacitor to VCC per datasheet recommendation.
27	CEO (A2)	Chip Enable Output (active Low) - signals end-of-data; used to cascade multiple AT17 devices in daisy-chain configuration.
29	CLK	Clock input - synchronized to FPGA CCLK; increments internal address/bit counter on rising edge.
35	DATA	Bi-directional open-collector I/O - outputs configuration data during FPGA load; used for 2-wire ISP programming.
38	VCC	+3.3V power supply - must be stable within ±10%; powers EEPROM core and I/O buffers.
44	SER_EN	Serial Enable - must be tied to VCC for FPGA configuration; pulled low to enter 2-wire ISP programming mode.
41	READY	Open-collector reset indicator - driven low during power-on reset, released (high-Z) when VCC stabilizes; requires 4.7 kΩ pull-up if used.

Key Features

Feature	Design Value
In-system programmability	Enables field updates of FPGA configuration without removing the device - achieved via 2-wire serial bus when SER_EN = Low.
Cascadable CEO output	Allows chaining multiple AT17LV002-10TQI units to support larger FPGAs or multi-FPGA systems - CEO of one drives CE of next.
Programmable reset polarity	EEPROM-stored setting allows RESET/OE to operate as either active-Low RESET or active-High OE - eliminates board-level logic for FPGA compatibility.
System-friendly READY pin	Provides hardware handshaking for FPGA power-up sequencing - ensures configuration begins only after stable VCC, reducing boot failures.
Low-power standby mode	Draws ≤200 µA with CE = High - ideal for battery-backed or energy-sensitive systems where configuration memory remains powered but inactive.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA configuration memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AT17LV002-10JI	Same 2-Mbit EEPROM core and 3.3V operation, but in 20-lead PLCC (20J) package - larger footprint, through-hole or surface-mount compatible.	Preferred for legacy PLCC-based designs or prototyping boards requiring manual soldering or socketing.	Select when board layout or mechanical constraints favor PLCC over TQFP; identical electrical behavior and timing.
AT17LV002-10TQC	Identical 44-lead TQFP package and 2-Mbit density, but rated for commercial temperature range (0°C to +70°C) instead of industrial.	Suitable for cost-sensitive consumer or lab-grade FPGA development kits where ambient temperature is controlled.	Choose for lower-cost procurement when industrial temperature qualification is unnecessary; same pinout and AC specs except FMAX derating.

Compared with AT17LV002-10JI and AT17LV002-10TQC, the AT17LV002-10TQI uniquely combines industrial temperature rating, TQFP compactness, and full feature set - making it optimal for production-grade embedded FPGA systems requiring long-term availability and thermal resilience.

FAQ

What is the primary function of the AT17LV002-10TQI in an FPGA system?

The AT17LV002-10TQI serves as a dedicated serial configuration EEPROM that stores and loads the bitstream into SRAM-based FPGAs during power-up or reset. It interfaces directly with FPGA control signals (CCLK, CE, INIT) in Master Serial mode, eliminating the need for external controllers. Its design ensures deterministic, repeatable FPGA initialization - a critical requirement for AT17LV002-10TQI deployments in industrial PLCs and telecom infrastructure.

Does the AT17LV002-10TQI support in-system programming (ISP), and how is it enabled?

Yes, the AT17LV002-10TQI supports in-system programming via a 2-wire serial interface. ISP is activated by driving the SER_EN pin Low, which places the device into programming mode - allowing field updates of the configuration bitstream without removal from the PCB. Programming occurs at the nominal 3.3V supply; no external high-voltage generator is needed because internal charge pumps generate required programming voltages. This capability is fully implemented in AT17LV002-10TQI and documented in Microchip's AT17 programming specification.

What does the READY pin on the AT17LV002-10TQI do, and how should it be used?

The READY pin on the AT17LV002-10TQI is an open-collector output that is actively driven Low during power-on reset and released (high-impedance) once VCC reaches a stable operating level. It provides hardware-level synchronization for FPGA startup - enabling the FPGA to delay configuration until power is valid. When used, a 4.7 kΩ pull-up resistor to VCC is required. This behavior is guaranteed across the full industrial temperature range of the AT17LV002-10TQI and improves system robustness against brown-out conditions.

Is the AT17LV002-10TQI pin-compatible with other packages in the AT17LV002 family?

Yes, the AT17LV002-10TQI is pin-compatible across all AT17LV002 variants - including the 8-lead LAP (8CN4), 20-lead PLCC (20J), and 44-lead PLCC (44J) - meaning identical signal assignments for functional pins (DATA, CLK, CE, RESET/OE, VCC, GND, SER_EN, READY, CEO). However, NC pin counts and locations differ by package; the 44-lead TQFP (44A) used in AT17LV002-10TQI has 31 NC pins, while the 20J has only 10. Layout reuse requires verifying NC pin exclusions per package drawing.

How does the AT17LV002-10TQI handle cascading for larger FPGA configurations?

The AT17LV002-10TQI supports cascading via its CEO (Chip Enable Output) pin, which goes Low when the internal address counter reaches its maximum value (end-of-memory). In a daisy chain, CEO of the first AT17LV002-10TQI connects to CE of the second, automatically enabling its DATA output upon completion of the first device's readout. This allows seamless extension of configuration memory beyond 2 Mbit using identical AT17LV002-10TQI units - a capability confirmed in the AT17C/LV002 datasheet Figure 5 and verified in Xilinx and Altera reference designs.
