Product details
Overview
AT17C512-10PC from Atmel is a 512-kilobit serial EEPROM FPGA configuration memory with 5V ±5% operation, 15 MHz max clock frequency, programmable reset polarity, and system-friendly READY pin. It serves as non-volatile configuration storage for SRAM-based FPGAs including Xilinx XC4000™, Spartan®, Virtex™, Altera FLEX®, and Atmel AT40K/AT94K devices in industrial temperature range (–40°C to +85°C).
For engineers reviewing the AT17C512-10PC datasheet, AT17C512-10PC pinout, AT17C512-10PC application, or AT17C512-10PC equivalent, key selection considerations include its 8-lead PDIP package compatibility, cascading CEO support for multi-FPGA systems, in-system programmability via 2-wire bus, low-power standby mode (<0.5 mA), and pin-level interoperability with legacy XC17/ATT17 PROMs.
Technical Context
The AT17C512-10PC implements a serial-access configuration memory architecture optimized for Master Serial Mode FPGA boot. Its internal address counter, bit counter, and tri-state DATA output are directly controlled by FPGA signals-CLK, CE, and RESET/OE-eliminating need for external controllers. The device supports daisy-chain cascading via CEO-to-CE interconnection and includes SER_EN-gated 2-wire ISP capability.
It features programmable reset polarity (RESET active Low / OE active High), write protection via WP1/WP2 inputs, and a power-on READY signal indicating stable VCC. All timing parameters-including TOE (30 ns), TCE (45 ns), TCAC (50 ns), and FMAX (15 MHz)-are specified for 5V ±5% commercial/industrial operation and validated across 8-lead PDIP, LAP, and 20-lead PLCC packages.

FAQ
What is the operating voltage range for AT17C512-10PC?
The AT17C512-10PC operates at 5V ±5% across the industrial temperature range (–40°C to +85°C). This specification ensures compatibility with standard 5V FPGA I/O banks and eliminates need for voltage translation circuitry when interfacing with legacy Xilinx, Altera, or Atmel FPGAs. The AT17C512-10PC does not support 3.3V operation-use AT17LV512-10PC for 3.3V systems.
Does AT17C512-10PC support in-system programming (ISP)?
Yes, AT17C512-10PC supports in-system programming via its 2-wire serial interface when SER_EN is driven Low. Programming occurs at the nominal VCC supply (5V), with internal charge pumps generating required programming voltages-no external high-voltage sources are needed. This capability allows field updates of FPGA configuration bitstreams without removing the AT17C512-10PC from the PCB.
How does the READY pin function on AT17C512-10PC?
The READY pin on AT17C512-10PC is an open-collector output that drives Low during power-on reset and releases (tri-states) once VCC reaches stable operating level. When used with a 4.7 kΩ pull-up resistor, it provides a clean reset synchronization signal to the FPGA's INIT or PROGRAM pin-ensuring configuration begins only after stable power, preventing corrupted bitstream loads. This behavior is confirmed in Figures 1–4 of the AT17C512 datasheet.
Can AT17C512-10PC be used in cascaded configurations?
Yes, AT17C512-10PC supports cascading via its CEO (Chip Enable Output) pin, which goes Low when the internal address counter reaches maximum value. In a daisy chain, CEO of the first AT17C512-10PC connects to CE of the second, enabling automatic handoff after completion of the first device's bitstream. This eliminates need for external logic to manage multi-device configuration sequencing.
Is AT17C512-10PC pin-compatible with older XC17 series PROMs?
Yes, AT17C512-10PC is a documented drop-in replacement for Xilinx XC17Cxx and Atmel ATT17xx PROMs in Xilinx/Lucent FPGA applications, as shown in Figure 2 of the datasheet. It maintains identical 8-lead PDIP pinout, timing parameters (TOE, TCE, TCAC), and functional behavior-including RESET/OE polarity and CEO signaling-enabling direct substitution without PCB modification.
