Product details
Overview
AT17C010A-10PC from Atmel is a 1-Mbit serial EEPROM FPGA configuration memory designed to store and load bitstream data for Altera FLEX® devices. It operates at 5V ±5%, supports cascaded daisy-chain configuration, features programmable reset polarity, includes a system-friendly READY pin (in PLCC/TQFP), and delivers configuration data via internal oscillator-driven DCLK in master mode. Used in industrial programmable logic systems requiring reliable, in-system reprogrammable configuration storage.
For engineers reviewing the AT17C010A-10PC datasheet, AT17C010A-10PC pinout, AT17C010A-10PC application, or AT17C010A-10PC equivalent, key selection criteria include 1-Mbit density, 5V operation, TQFP/PLCC/PDIP package options, cascading support via nCASC, and compatibility with Altera EPC1 replacement requirements.
Technical Context
The AT17C010A-10PC implements a dedicated serial configuration controller architecture with internal address counter, tri-state DATA output, and programmable OE/nCS handshaking logic. It supports both master mode (internal clock generation) and slave mode (external DCLK synchronization), enabling flexible integration into FPGA power-up sequences.
Its cascading capability relies on nCASC output assertion upon end-of-data, which triggers nCS of the next device in chain. The SER_EN pin enables 2-wire in-system programming, while WP1 provides selective memory write protection during programming - independent of FPGA configuration operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8-bit organization) - sufficient to configure Altera EPF10K-series and larger FLEX devices. |
| Supply Voltage | 5V ±5% - compatible with standard 5V industrial logic rails and ensures interoperability with legacy FPGA I/O voltage domains. |
| Operating Temperature | -40°C to +85°C - rated for industrial environments without derating, supporting embedded control and automation applications. |
| Max Clock Frequency | 12.5 MHz (cascaded mode) - defines maximum configuration data transfer rate when chained with other AT17A devices. |
| Standby Current | 0.5 mA at 5V - enables low-power hold state during FPGA idle periods without external power gating. |
| Output Drive | Open-collector READY pin with 4.7 kΩ pull-up recommended - provides synchronous reset coordination with FPGA nCONFIG timing. |
| Programming Interface | 2-wire serial (SER_EN-controlled) - allows field updates using Atmel ATDH2225 ISP cable or industry-standard programmers. |
Pinout & Package
AT17C010A-10PC is available in three packages: 8-lead PDIP (8P3), 20-lead PLCC (20J), and 32-lead TQFP (32A). Pin functions are identical across packages; however, READY and WP1 are only present in PLCC and TQFP variants. PDIP lacks READY and WP1 pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DATA | I/O bidirectional | Three-state configuration data output during FPGA load; open-collector bi-directional pin for 2-wire programming. |
| DCLK | I/O clock | Rising-edge clock output (master mode) or input (slave mode); controls internal address counter increment and data timing. |
| OE | Input | Active-High output enable / active-Low reset; resets address counter and tri-states DATA; polarity programmable for Altera compatibility. |
| nCS | Input | Active-Low chip select; determines master/slave initialization behavior and enables DATA output and counter operation. |
| nCASC | Output | Active-Low cascade select; signals end-of-data to trigger next device in daisy-chain; tied to nCS of downstream AT17A device. |
| READY | Output | Open-collector reset status indicator; driven Low during power-on reset, released (tri-stated) after VCC stabilization - used to synchronize FPGA nCONFIG. |
| SER_EN | Input | Serial enable; must be High during FPGA configuration; pulled Low to enter 2-wire in-system programming mode. |
| WP1 | Input | Write protect control; disables programming of protected memory regions; internally pulled down, unused during FPGA loading. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enabled via SER_EN pin and 2-wire interface - permits field firmware updates without socket removal or UV erasure. |
| Cascadable configuration | nCASC output drives nCS of next device - enables seamless expansion beyond 1-Mbit capacity for high-density FPGA arrays. |
| Programmable reset polarity | Four EEPROM bytes define OE behavior - ensures correct reset alignment with Altera FPGA nCONFIG timing requirements. |
| System-ready coordination | READY pin provides open-collector reset status - simplifies power sequencing by holding FPGA in reset until VCC stabilizes. |
| Low-power standby | ICCS ≤ 0.5 mA at 5V with nCS High - reduces system quiescent current during FPGA configuration idle states. |
Applications
| Industrial PLC Configuration Storage | Automated Test Equipment (ATE) FPGA Initialization |

FAQ
What is the primary function of the AT17C010A-10PC in an FPGA system?
The AT17C010A-10PC serves as a dedicated serial configuration EEPROM that stores and loads the bitstream required to initialize Altera FLEX® FPGAs. It autonomously clocks configuration data to the FPGA's DATA0 pin using its internal oscillator in master mode, eliminating the need for an external controller. Its design ensures deterministic startup timing and supports both single-device and cascaded multi-device configurations.
Does the AT17C010A-10PC support in-system programming, and how is it enabled?
Yes, the AT17C010A-10PC supports in-system programming via a 2-wire serial interface. Programming mode is activated by driving the SER_EN pin Low while maintaining VCC within specification. During this mode, the device accepts write commands through the DATA and DCLK pins. The WP1 pin can be used to protect specific memory regions from unintended writes, and programming voltages are generated internally - no external high-voltage supply is needed.
Which packages are available for the AT17C010A-10PC, and which pins differ between them?
The AT17C010A-10PC is offered in 8-lead PDIP (8P3), 20-lead PLCC (20J), and 32-lead TQFP (32A) packages. All share identical core functionality and pin assignments for DATA, DCLK, OE, nCS, nCASC, SER_EN, VCC, and GND. However, the READY and WP1 pins are absent in the PDIP variant but present in both PLCC and TQFP packages - making PDIP suitable for cost-sensitive, non-READY applications.
How does the READY pin on the AT17C010A-10PC coordinate with FPGA power-up sequencing?
The READY pin on the AT17C010A-10PC is an open-collector output driven Low during the internal power-on reset cycle and released (tri-stated) once VCC has stabilized and internal circuitry is ready. When externally pulled up, it provides a clean reset signal to the FPGA's nCONFIG pin, ensuring configuration begins only after stable supply conditions are met - preventing partial or failed configuration due to premature power ramping.
Can the AT17C010A-10PC be used to replace Altera EPC1 devices, and what documentation confirms this?
Yes, Atmel's official documentation (Ordering Information section, Note 2) explicitly states "Use 1-Mbit density parts to replace Altera EPC1." The AT17C010A-10PC matches EPC1's 1-Mbit density, 5V operation, PDIP/PLCC/TQFP packaging options, and functional timing - enabling direct substitution in legacy Altera reference designs without layout modification, provided OE polarity is programmed correctly during initial setup.
