Microchip Technology AT17N010-10PC

Overview

AT17N010-10PC from Atmel is a 1-Mbit (1,048,576 × 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 XC17SXXXA/L PROMs, low-power standby mode (<100 µA industrial), and 20-year data retention at 85°C.

For engineers reviewing the AT17N010-10PC datasheet, AT17N010-10PC pinout, AT17N010-10PC application, or AT17N010-10PC equivalent, this device serves as a drop-in replacement for legacy Xilinx-compatible configuration PROMs in SRAM-based FPGA systems requiring reliable, nonvolatile, serial-programmable boot memory with industrial temperature support.

Technical Context

The AT17N010-10PC implements a simple serial-access interface synchronized to an external FPGA-provided CCLK signal, enabling direct master-mode configuration without host controller intervention. Its internal address counter advances on CLK rising edges, and DATA output is tri-stated via RESET/OE (active-low reset, active-high OE) and CE (active-low chip enable).

It supports two operational modes: normal FPGA configuration (SER_EN = VCC) and Two-Wire Serial In-System Programming (SER_EN = Low). The device uses a high-reliability CMOS EEPROM process with guaranteed 10 write cycles and operates across -40°C to +85°C industrial range with 3.0V–3.6V supply tolerance.

FAQ

What is the primary function of the AT17N010-10PC in an FPGA system?

The AT17N010-10PC serves as a serial configuration EEPROM that stores and delivers the bitstream to SRAM-based FPGAs-including Xilinx Spartan-II, Spartan-IIE, and Spartan XL-in Master Serial mode. It eliminates the need for external controllers by directly interfacing with FPGA control signals (CCLK, DIN, INIT_B), and AT17N010-10PC ensures deterministic, repeatable power-on configuration with no software overhead.

Is the AT17N010-10PC pin-compatible with Xilinx XC17S100A PROMs?

Yes, the AT17N010-10PC is explicitly designed to be pin-compatible with Xilinx XC17SXXXA and XC17SXXXXL PROMs, including the XC17S100A. This compatibility extends to electrical timing (TCE ≤60 ns, TCAC ≤60 ns), package footprint (20-lead SOIC), and functional pin mapping-enabling direct replacement in existing Spartan-II designs without PCB or firmware changes.

What programming methods does the AT17N010-10PC support?

The AT17N010-10PC supports both standard serial programming (via industry-standard programmers or Atmel's ATDH2200E kit) and Two-Wire In-System Programming (ISP) enabled by pulling the VCC(SER_EN) pin low. ISP allows field updates using only the DATA and CLK lines-no dedicated programming header or external voltage is needed-and AT17N010-10PC retains full functionality during normal FPGA operation.

Does the AT17N010-10PC support industrial temperature operation?

Yes, the AT17N010-10PC is rated for industrial temperature operation from -40°C to +85°C, as confirmed by its ordering code suffix "I" (e.g., AT17N010-10SI) and validated in the Absolute Maximum Ratings and Operating Conditions tables. The "-10PC" variant is commercial grade (0°C to +70°C), but AT17N010-10PC shares identical core functionality and packaging with its industrial sibling AT17N010-10SI.

How does the AT17N010-10PC enter low-power standby mode?

The AT17N010-10PC enters low-power standby mode when the CE (Chip Enable) pin is driven high, disabling its internal address counter and tri-stating the DATA output. In this state, AT17N010-10PC draws less than 100 µA at 3.3V and 85°C-reducing system-level power consumption during FPGA idle periods or partial reconfiguration sequences without interrupting configuration readiness.
