Product details
Overview
AT17C010A-10QC from Atmel is a 1-Mbit serial EEPROM FPGA configuration memory designed to store and serially load bitstream data into Altera FLEX® devices. It operates at 5V ±5%, supports cascaded daisy-chain configuration, features programmable reset polarity, and includes a system-friendly READY pin in its 32-lead TQFP package for power-up synchronization.
For engineers reviewing the AT17C010A-10QC datasheet, AT17C010A-10QC pinout, AT17C010A-10QC application, or AT17C010A-10QC equivalent, key selection criteria include cascade support (nCASC), in-system programmability via SER_EN, open-collector READY timing behavior, and compatibility with Altera's serial configuration protocol using DCLK/OE/nCS control signals.
Technical Context
The AT17C010A-10QC implements a dedicated serial configuration controller architecture with internal address counter, oscillator, and tri-state DATA output. It functions as either master (generating DCLK) or slave (accepting external DCLK), determined by SER_EN and nCS initialization state during power-up reset.
Its cascading logic uses nCASC (active-Low) to chain multiple devices: when one device completes transmission, it asserts nCASC to enable the next device's nCS. The READY pin provides open-collector power-on reset status indication, synchronized to internal VCC stabilization-not system rail stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (131,072 × 8) EEPROM array for full FPGA configuration storage |
| Supply Voltage | 5V ±5% - supports commercial temperature range (0°C to +70°C) |
| Package | 32-lead TQFP (32A), 1.0 mm profile, gull-wing leads - space-efficient surface-mount |
| Configuration Interface | Serial master/slave mode with DCLK, OE, nCS, DATA - direct pinout match to Altera EPF10K series |
| Ready Signal | Open-collector READY pin - driven Low during internal power-on reset, tri-stated on completion |
| Cascade Support | nCASC output - active-Low signal to trigger next device in daisy-chain configuration |
| Programming Mode | SER_EN-controlled 2-wire serial programming - enables in-system reprogramming without socket removal |
Pinout & Package
AT17C010A-10QC is housed in a 32-lead Thin Quad Flat Package (TQFP, JEDEC 32A), 10 mm × 10 mm body, 1.0 mm max height, gull-wing leads. Pin 1 marked with corner notch; lead pitch 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connect - unused internal node, must be left floating or grounded per layout guidelines |
| 2 | DCLK | Configurable clock I/O - outputs internal oscillator clock (master mode) or accepts external clock (slave mode) |
| 3–4 | NC | No connect - electrically isolated; no routing required |
| 5 | WP1 | Write protect input - enables partial memory lock during ISP; disabled by default (internal pull-down) |
| 6–7 | NC | No connect - unused; avoid routing or loading |
| 8 | OE | Output enable / reset input (active-High OE, active-Low reset) - resets address counter and disables DATA output |
| 9–10 | NC | No connect - reserved; leave unconnected |
| 11 | SER_EN | Serial enable input - must be High for FPGA configuration; Low enables 2-wire ISP programming mode |
| 12–14 | NC | No connect - not bonded; no electrical function |
| 15 | READY | Open-collector reset status indicator - Low during internal POR, tri-stated after completion; requires 4.7 kΩ pull-up if used |
| 16–17 | NC | No connect - unused; no PCB trace needed |
| 18 | nCS | Chip select input (active-Low) - enables counter and DATA output; determines master/slave role at power-up |
| 19–20 | NC | No connect - electrically inactive |
| 21 | GND | Ground reference - decoupling capacitor (0.2 µF) required between this and VCC |
| 22 | nCASC | Cascade select output (active-Low) - signals end-of-data to next device in daisy-chain |
| 23 | A2 | Device address input - used only during 2-wire programming to select target device |
| 24–25 | NC | No connect - not functional; leave unconnected |
| 26 | DATA | Bi-directional open-collector data I/O - outputs configuration bitstream; inputs programming data in SER_EN mode |
| 27–31 | NC | No connect - internal test or reserve; no connection required |
| 32 | VCC | +5V power supply - must be stabilized before READY release; bypassed with 0.2 µF ceramic capacitor |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enabled via SER_EN pin - allows field updates of FPGA configuration data without device removal |
| Cascadable configuration | nCASC output synchronizes multi-device chains - eliminates need for external sequencers in high-density FPGA systems |
| Programmable reset polarity | User-configurable OE/RESET logic - ensures compatibility with Altera's active-Low nCONFIG requirement |
| System-ready signaling | READY pin provides deterministic power-on reset status - simplifies FPGA nCONFIG timing coordination |
| Altera EPC1 drop-in replacement | Pin- and protocol-compatible with Altera EPC1 - enables direct migration in existing FLEX® designs |
| Low-power standby | ICCS < 0.5 mA at 5V - achieved by holding nCS High; maintains zero-power idle state post-configuration |

FAQ
What is the operating voltage range for AT17C010A-10QC?
The AT17C010A-10QC is rated for 5V ±5% supply voltage and specified for commercial temperature range (0°C to +70°C). It draws up to 10 mA in active configuration mode and less than 0.5 mA in standby (nCS High). Operation outside this range risks timing violations or data corruption - always verify VCC stability before READY release.
How does the READY pin function in AT17C010A-10QC?
The READY pin on AT17C010A-10QC is an open-collector output that drives Low during internal power-on reset and releases (tri-states) upon completion. It reflects internal VCC stabilization - not system rail readiness - and requires a 4.7 kΩ pull-up resistor. It is used to hold FPGA nCONFIG in reset until the EEPROM is ready to begin configuration.
Can AT17C010A-10QC be used in cascaded FPGA configurations?
Yes, AT17C010A-10QC supports daisy-chain configuration via its nCASC output. When the device finishes transmitting its 1-Mbit bitstream, it asserts nCASC (active-Low) to enable the nCS input of the next AT17C010A-10QC or compatible device. This enables seamless expansion beyond single-FPGA capacity without external control logic.
Is AT17C010A-10QC pin-compatible with Altera EPC1?
Yes, AT17C010A-10QC is a direct pin- and protocol-compatible replacement for Altera EPC1 in 32-lead TQFP packages. It matches EPC1's DCLK/OE/nCS/DATA interface, memory map, and timing sequence - enabling drop-in upgrades with added features including READY, SER_EN, and WP1.
What programming interface does AT17C010A-10QC support?
AT17C010A-10QC supports in-system programming via a 2-wire serial interface activated by pulling SER_EN Low. Programming occurs at VCC (5V) with internally generated high voltages - no external VPP required. It is compatible with Atmel's ATDH2225 ISP cable and industry-standard programmers supporting the AT17A Series command set.
