Product details

Overview

AT17N512-10PC from Atmel is a 512-Kbit (524,288 × 1-bit) serial EEPROM FPGA configuration memory operating at 3.3V ±10%, designed for Master Serial mode loading of Xilinx Spartan-II, Spartan-IIE, and Spartan XL FPGAs. It features pin compatibility with Xilinx XC17SXXXA/L PROMs, low-power standby current ≤100 µA (industrial), and 20-year data retention at 85°C.

For engineers reviewing the AT17N512-10PC datasheet, AT17N512-10PC pinout, AT17N512-10PC application, or AT17N512-10PC equivalent, key selection criteria include serial interface timing (f_MAX = 15 MHz commercial / 10 MHz industrial), CE/RESET/OE control logic for FPGA-synchronized configuration, package-specific pin mapping (8-lead PDIP), and EEPROM endurance (≥10 write cycles).

Technical Context

The AT17N512-10PC implements a simple serial-access architecture where FPGA-generated CCLK drives the CLK input to increment the internal address counter, while DATA output feeds the FPGA's DIN pin. SER_EN must be tied to VCC during normal configuration, enabling direct FPGA-controlled startup without external controllers.

Its dual-mode operation supports standard Master Serial loading (SER_EN = VCC) and Two-Wire In-System Programming (SER_EN = Low), with all programming voltages generated internally-no external high-voltage supply required. The device enters low-power standby (<100 µA) when CE is held High, independent of RESET/OE state.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory density	512-Kbit (524,288 × 1-bit) serial EEPROM for full FPGA bitstream storage
Supply voltage	3.3V ±10% - compatible with standard 3.3V FPGA I/O rails and eliminates level-shifting needs
Max clock frequency	15 MHz (commercial), 10 MHz (industrial) - sets upper bound on configuration speed in Master Serial mode
Standby current	≤100 µA (industrial) - enables ultra-low power hold state during FPGA reset or idle periods
Data retention	20 years at 85°C - ensures long-term reliability in industrial temperature environments
Endurance	Minimum 10 write cycles - sufficient for factory programming and limited field reconfiguration
Operating temperature	-40°C to +85°C (industrial grade) - validated for embedded systems in harsh thermal conditions

Pinout & Package

AT17N512-10PC is packaged in an 8-lead Plastic Dual Inline Package (PDIP), 0.300" wide, with JEDEC-standard pin layout and through-hole mounting compatibility.

Pin/Terminal	Circuit Role	Design Meaning
1: DATA	I/O (Three-state open-collector)	Bi-directional serial data path: outputs configuration bits to FPGA DIN during load; accepts programming data in ISP mode
2: CLK	Input	Asynchronous clock input synchronized to FPGA CCLK; increments internal address/bit counter on rising edge
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 controlling address counter and DATA driver; High forces low-power standby regardless of RESET/OE state
5: GND	Power ground	Reference return path; requires 0.2 µF decoupling capacitor between VCC and GND per datasheet recommendation
6: DC	Output (No Connect)	Internally connected die connection point - not bonded externally; must remain unconnected in PCB layout
7: VCC(SER_EN)	Input	Serial enable: must be tied to VCC for FPGA configuration; Low enables Two-Wire ISP mode
8: VCC	Power supply	3.3V ±10% main supply; powers EEPROM core and I/O buffers; shared with SER_EN function on pin 7

Key Features

Feature	Design Value
Pin compatibility	Fully pin-compatible with Xilinx XC17SXXXA and XC17SXXXXL PROMs - enables drop-in replacement in legacy Spartan-based designs
Interface simplicity	Direct connection to SRAM-based FPGAs via three control signals (CLK, CE, RESET/OE) and one DATA line - no glue logic or microcontroller required
Two-Wire ISP support	Internal voltage generation allows in-system programming using only SER_EN and DATA pins - eliminates need for external HV programming hardware
Low-power standby	CE-driven standby draws ≤100 µA (industrial) - reduces system-level quiescent power without disabling configuration memory
High-reliability EEPROM	20-year data retention at 85°C and ≥10 write cycles - meets industrial lifecycle requirements for unattended embedded deployments

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 XC17S512A	OTP PROM (one-time programmable); no reprogrammability; identical 8-lead PDIP pinout and AC timing	Requires pre-programmed bitstream; unsuitable for field updates or prototyping iterations	Select when configuration is fixed and security against tampering is prioritized over flexibility
Microchip (Atmel) AT17LV512-10CU	Lower 2.5V–3.6V supply range; enhanced 100K-cycle endurance; same 512-Kbit density and PDIP packaging	Supports mixed-voltage systems and frequent reprogramming; newer product with active production status	Select for new designs requiring longer EEPROM lifetime or broader voltage margin than AT17N512-10PC offers

Compared with Xilinx XC17S512A, AT17N512-10PC provides reprogrammability and lower standby power but shares identical pinout and FPGA interface timing; versus AT17LV512-10CU, it trades reduced endurance and narrower voltage tolerance for established qualification in legacy industrial systems.

FAQ

What is the maximum clock frequency supported by AT17N512-10PC in industrial temperature range?

The AT17N512-10PC supports a maximum clock frequency of 10 MHz under industrial operating conditions (-40°C to +85°C), as specified in the AC Characteristics table. This defines the upper limit for configuration data transfer rate when interfacing with Spartan-II or Spartan-IIE FPGAs in Master Serial mode. Exceeding this frequency may result in read errors or incomplete bitstream loading.

Is AT17N512-10PC pin-compatible with Xilinx XC17S512A PROMs?

Yes, AT17N512-10PC is explicitly pin-compatible with Xilinx XC17S512A PROMs in the 8-lead PDIP package, sharing identical pin assignments for DATA, CLK, RESET/OE, CE, GND, VCC(SER_EN), and VCC. This enables direct substitution in existing Spartan-II designs without PCB modifications, though functional differences (EEPROM vs. OTP) must be considered.

How does the SER_EN pin affect AT17N512-10PC operation?

The SER_EN pin (shared with VCC on pin 7) determines operational mode: when held High (tied to VCC), AT17N512-10PC operates in standard FPGA configuration mode; when pulled Low, it enters Two-Wire In-System Programming mode, enabling field reprogramming via DATA and CLK pins without external high-voltage sources. For normal use, SER_EN must be connected to VCC.

What is the standby current consumption of AT17N512-10PC at 85°C?

At 85°C and industrial grade, AT17N512-10PC consumes ≤100 µA in standby mode when CE is held High. This value is confirmed in the DC Characteristics table and reflects worst-case current draw under maximum operating temperature, critical for thermal-aware power budgeting in sealed industrial enclosures.

Can AT17N512-10PC be used with Spartan-XL FPGAs?

Yes, AT17N512-10PC is explicitly stated as compatible with Xilinx Spartan XL FPGAs in Master Serial mode per the device description and FPGA Master Serial Mode Summary sections. It supports the same serial interface protocol, timing parameters, and control signal mapping required by Spartan XL devices for automatic power-up configuration loading.
