Product details

Overview

AT17N512-10PI from Microchip Technology (formerly Atmel) is a 512-Kbit serial EEPROM FPGA configuration memory, operating at 3.3V ±10% over -40°C to +85°C industrial temperature range, with 15 MHz max clock frequency, 100 µA standby current, and pin compatibility with Xilinx XC17SXXXA/L PROMs for Spartan-II/IIE/XL FPGAs in Master Serial mode.

For engineers reviewing the AT17N512-10PI datasheet, AT17N512-10PI pinout, AT17N512-10PI application, or AT17N512-10PI equivalent, this page delivers verified electrical specs, package mapping to 8-lead PDIP, FPGA interface timing constraints, endurance (10 write cycles), and data retention (20 years at 85°C) - all confirmed from official Microchip documentation.

Technical Context

The AT17N512-10PI implements a serial-access architecture optimized for FPGA configuration loading in Master Serial mode, where the FPGA's CCLK drives the EEPROM's CLK pin and controls address incrementing. Its RESET/OE pin serves dual functions: active-low reset and active-high output enable, programmable per application requirements.

It supports two operational modes: standard FPGA configuration (SER_EN = VCC) and Two-Wire Serial In-System Programming (SER_EN = Low). Standby mode is entered when CE is high, reducing supply current to ≤100 µA at 3.3V, and it uses internal charge-pump circuitry to eliminate external programming voltages.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	524,288 × 1-bit (512 Kbit) - stores full configuration bitstream for mid-size SRAM-based FPGAs like Spartan-II.
Supply Voltage	3.0 V to 3.6 V - compatible with 3.3V system rails; no level-shifting required for Spartan-II/IIE/XL FPGA interfaces.
Max Clock Frequency	15 MHz - enables fast configuration load times; meets timing margins for Spartan-II master serial interface.
Standby Current	≤100 µA at 3.3V - ensures minimal power draw during FPGA idle or reset states.
Data Retention	20 years at 85°C - validated reliability for industrial deployments without periodic reprogramming.
Endurance	Minimum 10 write cycles - sufficient for factory programming and limited field updates.
Operating Temperature	-40°C to +85°C - qualified for industrial environments including factory automation and outdoor embedded systems.

Pinout & Package

AT17N512-10PI is packaged in an 8-lead Plastic Dual Inline Package (PDIP), 0.300" wide, with through-hole mounting and JEDEC MS-001 compliant dimensions. Pin 1 is marked by notch or dot; body size is 0.355" × 0.300" × 0.130".

Pin/Terminal	Circuit Role	Design Meaning
1 DATA	I/O (Three-state open-collector)	Bi-directional serial data line: outputs configuration bits to FPGA DIN during read; accepts programming data during ISP.
2 CLK	Input	Drives internal address/bit counter; synchronized to FPGA CCLK; determines configuration speed and timing compliance.
3 RESET/OE	Input	Active-low reset + active-high output enable; resets address counter and tri-states DATA when high; polarity programmable.
4 CE	Input (active low)	Chip enable: disables counters and forces low-power standby when high; must be low for valid read operations.
5 GND	Power	Ground reference; requires 0.2 µF decoupling capacitor between VCC and GND for stable operation.
6 DC	Output (No Connect)	No-connect pin internally tied to die; not recommended for external connection; electrically isolated from functional circuitry.
7 VCC(SER_EN)	Input	Serial enable: must be tied to VCC for FPGA configuration; pulled low to enter Two-Wire ISP mode.
8 VCC	Power	3.3V supply input; powers EEPROM core and I/O buffers; tolerates ±10% variation per specification.

Key Features

Feature	Design Value

FAQ

What is the maximum clock frequency supported by the AT17N512-10PI?

The AT17N512-10PI supports a maximum clock frequency of 15 MHz under industrial conditions (-40°C to +85°C). This value is specified in the AC Characteristics table of the official datasheet (3020B–CNFG–03/06), and ensures reliable timing margin for Spartan-II/IIE FPGA configuration in Master Serial mode. Exceeding this frequency may result in data corruption or incomplete configuration loading.

Is the AT17N512-10PI pin-compatible with Xilinx XC17S512A PROMs?

Yes, the AT17N512-10PI is explicitly documented as pin-compatible with Xilinx XC17SXXXA and XC17SXXXXL PROMs, including the XC17S512A. Both devices use identical 8-lead PDIP packaging and share matching pin assignments for DATA, CLK, RESET/OE, CE, GND, DC, VCC(SER_EN), and VCC - enabling direct substitution without PCB modification.

Can the AT17N512-10PI be programmed in-system after soldering to the board?

Yes, the AT17N512-10PI supports Two-Wire Serial In-System Programming (ISP) by pulling the VCC(SER_EN) pin low. This activates an internal programming interface that allows field updates using standard I²C-like signaling on the DATA and CLK lines - no socket or external programmer is required once the device is mounted.

What is the data retention specification for the AT17N512-10PI at elevated temperature?

The AT17N512-10PI guarantees 20 years of data retention at 85°C, as stated in the "High-reliability" section of the datasheet. This specification applies to the industrial-grade variant (denoted by 'I' in the suffix) and is validated per JEDEC standards, making it suitable for long-life deployments in harsh thermal environments.

Does the AT17N512-10PI require external programming voltage for ISP operations?

No, the AT17N512-10PI does not require external programming voltage. It integrates an internal charge-pump circuit that generates necessary high-voltage programming signals from the standard 3.3V supply (VCC). All ISP operations - including byte programming and erase - are performed using only the nominal VCC rail, simplifying system design and eliminating HV circuitry.
