Product details
Overview
AT17LV128-10PI from Atmel is a 128-Kbit serial FPGA configuration EEPROM designed to store and load bitstreams for SRAM-based FPGAs in industrial environments (−40°C to +85°C). It supports dual-voltage operation (3.3V ±10% or 5.0V ±10%), features in-system programmability via two-wire bus, and provides cascading capability through CEO output for multi-FPGA systems.
For engineers reviewing the AT17LV128-10PI datasheet, AT17LV128-10PI pinout, AT17LV128-10PI application, or AT17LV128-10PI equivalent, key selection criteria include industrial temperature rating, 8-lead PDIP package compatibility, programmable reset polarity, low-power standby mode (<100 µA at 3.3V), and verified interoperability with Xilinx XC3000/XC4000, Altera FLEX/APEX, and Atmel AT40K/AT94K devices.
Technical Context
The AT17LV128-10PI implements a serial master-configuration interface where CLK drives internal address/bit counters, CE enables data output and controls standby current, and RESET/OE resets counters and tri-states DATA. Its CEO output enables daisy-chain configuration of multiple FPGAs by asserting CE of the next device upon completion of readout.
It uses a CMOS EEPROM process with programmable reset polarity (RESET/OE or RESET/OE), write-protection via WP pin (active-low during programming), and SER_EN-controlled mode switching between FPGA loading (SER_EN = High) and ISP (SER_EN = Low). The device does not support READY or A2 pins - features reserved for higher-density variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 128 Kbit (131,072 × 1-bit) nonvolatile EEPROM storage for FPGA configuration bitstreams |
| Operating voltage | 3.3 V ±10% or 5.0 V ±10% - supports mixed-voltage system integration without level-shifting |
| Temperature range | Industrial: −40°C to +85°C - qualified for harsh embedded and industrial control environments |
| Standby current | <100 µA at 3.3 V - enables low-power system sleep modes when CE is high |
| Write endurance | 100,000 program/erase cycles - sufficient for field reconfiguration and firmware updates |
| Data retention | 90 years at 85°C - ensures long-term reliability in unattended deployments |

Pinout & Package
AT17LV128-10PI is supplied in an 8-lead plastic dual in-line package (PDIP), 0.300" wide, with JEDEC-standard footprint and pinout compatible with industry-standard socketing and PCB layout practices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - DATA | I/O (open-collector) | Bi-directional serial data path: outputs configuration bits to FPGA DIN during load; accepts programming data during ISP |
| 2 - CLK | Input | Drives internal address and bit counters; synchronized to FPGA CCLK for deterministic bitstream delivery |
| 3 - RESET/OE | Input | Active-Low reset + active-High output enable; polarity programmable to match FPGA reset logic convention |
| 4 - CE | Input (active Low) | Enables read operation and disables standby mode; tri-states DATA when high |
| 5 - GND | Power reference | Ground return for all signals; requires 0.2 µF decoupling capacitor near VCC pin |
| 6 - CEO | Output (active Low) | Signals end-of-data to next cascaded EEPROM; enables automatic daisy-chain sequencing without external logic |
| 7 - SER_EN | Input | High = FPGA configuration mode; Low = two-wire ISP mode - must be tied to VCC for normal operation |
| 8 - VCC | Power supply | Accepts 3.3 V ±10% or 5.0 V ±10%; supports dual-voltage board designs |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Xilinx XC18V02 | 2-Mbit capacity; supports only 3.3 V operation; no CEO pin; requires external pull-ups on DATA/CLK | Higher density but lacks cascading support and industrial temperature grade (only commercial: 0°C–70°C) | Select when >128 Kbit storage is required and cascading is unnecessary; verify voltage compatibility with target FPGA |
| Microchip 25LC1024 | 1-Mbit SPI EEPROM; no built-in FPGA interface logic; requires external controller for configuration sequencing | General-purpose SPI memory - not optimized for FPGA master-serial boot; no CEO, RESET/OE, or SER_EN pins | Choose only if existing system already uses SPI infrastructure and FPGA configuration is handled by MCU; adds software/firmware overhead |
Compared with XC18V02 and 25LC1024, the AT17LV128-10PI delivers purpose-built FPGA configuration functionality - including CEO-driven daisy-chaining, programmable reset polarity, and industrial temperature qualification - without requiring external sequencing logic or compromising on reliability.

FAQ
What is the memory capacity and organization of the AT17LV128-10PI?
The AT17LV128-10PI provides 128 Kbit (131,072 × 1-bit) of serial EEPROM storage, organized as a linear bitstream memory optimized for sequential FPGA configuration loading. It does not support random-access addressing or byte-level writes outside of ISP mode, and its architecture is dedicated solely to master-serial bitstream delivery - not general-purpose data storage.
Does the AT17LV128-10PI support both 3.3 V and 5.0 V FPGA families?
Yes, the AT17LV128-10PI supports dual-voltage operation: 3.3 V ±10% and 5.0 V ±10%. This allows direct interfacing with both 3.3 V and 5.0 V SRAM-based FPGAs such as Xilinx XC4000, Altera FLEX 10K, and Atmel AT40K without level-shifting circuitry - verified across industrial temperature conditions (−40°C to +85°C).
How does cascading work with the AT17LV128-10PI in multi-FPGA systems?
The AT17LV128-10PI uses its CEO (Chip Enable Output) pin to cascade with other AT17LV-series devices: when the internal counter reaches the final address, CEO asserts Low, enabling the CE input of the next device in the chain. This hardware-automated sequencing eliminates external logic or software coordination - a core feature confirmed for AT17LV128-10PI in the official datasheet.
Is the AT17LV128-10PI pin-compatible with other packages in the AT17LV family?
No - the AT17LV128-10PI (8-lead PDIP) shares pinout compatibility only with AT17LV65/128/256 variants, but not with AT17LV512/010/002/040 devices. Pin compatibility is explicitly limited to the 8-lead LAP, PDIP, and SOIC packages for this density tier; migration to higher-density variants requires PCB redesign due to differing pin functions and counts.
What programming methods are supported by the AT17LV128-10PI?
The AT17LV128-10PI supports two programming modes: standard FPGA configuration loading (SER_EN = High) and in-system programming (SER_EN = Low, two-wire serial bus). Programming is performed at VCC voltage only - no external high-voltage supplies are needed - and is compatible with Atmel's ATDH2200E kit and industry-standard programmers per datasheet Section 9.
