Product details
Overview
AT17LV010A-10JI from Atmel is a 1-Mbit (1,048,576 × 1-bit) FPGA configuration EEPROM designed for serial loading of SRAM-based FPGAs including Altera FLEX® and APEX™, Xilinx Spartan® and Virtex®, and Lucent ORCA® devices. It operates at 3.3V (±10%) or 5.0V (±10% industrial), supports in-system programming via 2-wire bus, features programmable reset polarity, and delivers 90-year data retention at 85°C. Its primary role is nonvolatile storage and sequential delivery of bitstream configuration data during FPGA power-up.
For engineers reviewing the AT17LV010A-10JI datasheet, AT17LV010A-10JI pinout, AT17LV010A-10JI application, or AT17LV010A-10JI equivalent, key selection criteria include industrial temperature support (–40°C to +85°C), cascading capability via nCASC/nCS daisy-chain, low-power standby current (100 µA at 3.3V), WP1 write-protection pin availability, and compatibility with legacy Atmel AT24CXXX serial EEPROM emulation.
Technical Context
The AT17LV010A-10JI implements a serial-access, master-controlled configuration memory architecture where FPGA-generated DCLK drives the internal address counter and DATA output. Its RESET/OE pin serves dual functions-active-Low reset and active-High output enable-with polarity programmable during programming to match FPGA requirements (e.g., Altera's RESET Low/OE High default).
Cascading is enabled through dedicated nCASC (output) and nCS (input) pins, allowing daisy-chained configuration of multiple FPGAs or higher-density arrays without external logic. The device enters low-power standby (<100 µA at 3.3V) when nCS is held High, and supports ISP only when SER_EN is driven Low-otherwise SER_EN must be tied to VCC during FPGA loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 1,048,576 × 1-bit (1 Mbit) - stores full configuration bitstream for mid-range SRAM FPGAs like Altera EPC1 or Xilinx XC4000 derivatives. |
| Supply voltage | 3.3V ±10% or 5.0V ±10% (industrial) - dual-voltage operation enables drop-in replacement across legacy 5V and modern 3.3V FPGA systems. |
| Operating temperature | –40°C to +85°C - qualified for industrial environments, enabling use in factory automation, motor control, and outdoor embedded systems. |
| Write endurance | 100,000 cycles - sufficient for repeated reconfiguration during development, field updates, or manufacturing test cycles. |
| Data retention | 90 years at 85°C - ensures long-term reliability in unattended or maintenance-limited deployments without bitstream corruption. |
| Standby current | 100 µA at 3.3V (industrial) - minimizes system-level quiescent power when FPGA is idle or in sleep mode. |
| Max clock frequency | 15 MHz (3.3V, commercial); 10 MHz (3.3V, industrial) - supports fast configuration load times while maintaining timing margin under worst-case voltage/temperature. |
Pinout & Package
AT17LV010A-10JI is supplied in a 20-lead Plastic Leaded Chip Carrier (PLCC) package, pin-compatible across the AT17LV family. This surface-mount package offers robust thermal performance (θJA = 90°C/W) and mechanical stability for industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DATA) | Bi-directional I/O | Three-state open-collector output during configuration; bidirectional for 2-wire ISP programming - interfaces directly to FPGA DIN or programmer SDA. |
| 2 (DCLK) | Input/Output | Rising-edge clock input from FPGA or external source; drives Low as master when configuration complete - synchronizes bitstream delivery and controls address counter increment. |
| 3 (WP1) | Input | Write-protect enable for upper memory blocks - active-High disables writes to protected regions; internal pull-down defaults to unprotected state. |
| 4 (RESET/OE) | Input | Programmable polarity pin: active-Low resets address counter and tri-states DATA; active-High enables DATA output - matches Altera/Xilinx FPGA reset timing requirements. |
| 5 (nCS) | Input | Chip select (active-Low): enables counter and DATA drive; determines master/slave role in cascade - Low at power-up initializes as master configurator. |
| 6 (GND) | Power | Ground reference for all signals and internal circuitry - requires local 0.2 µF decoupling capacitor per datasheet recommendation. |
| 7 (nCASC) | Output | Cascade select (active-Low): asserts when final bit is read - connects to nCS of next device in chain to enable automatic multi-device configuration sequencing. |
| 8 (A2) | Input | Device selection during ISP programming - used with SER_EN Low to address specific device in multi-unit programming fixtures. |
| 9 (READY) | Output | Open-collector power-on reset indicator - driven Low during internal POR, released after stabilization; requires external 4.7 kΩ pull-up if monitored. |
| 10 (SER_EN) | Input | Serial enable: must be High during FPGA configuration; Low enables 2-wire ISP mode - tied to VCC in production systems to disable programming access. |
| 11–19 (NC) | No-connect | Not internally bonded - left unconnected on PCB; no electrical or thermal impact. |
| 20 (VCC) | Power | Primary supply input for both configuration and ISP modes - accepts 3.3V or 5V with specified tolerance; powers internal charge pumps for programming. |

FAQ
What is the operating temperature range of the AT17LV010A-10JI?
The AT17LV010A-10JI is rated for industrial operation from –40°C to +85°C. This specification is validated per datasheet Section 8 (Operating Conditions) and confirmed by thermal resistance data (θJA = 90°C/W) in the PLCC package. The device maintains full functionality-including 15 MHz max clock rate and 100 µA standby current-across this full range, making it suitable for harsh-environment applications where commercial-grade parts would fail.
Does the AT17LV010A-10JI support in-system programming (ISP)?
Yes, the AT17LV010A-10JI supports ISP via a 2-wire serial interface when SER_EN is driven Low. During ISP, the DATA and DCLK pins function as bidirectional SDA/SCL lines, and A2 serves as a device-select input. Programming occurs at VCC voltage only-no external high-voltage supply is needed-as internal charge pumps generate required programming voltages. This capability is documented in Section 7 ("Programming Mode") of the datasheet.
How does the nCASC pin function in a daisy-chain configuration with the AT17LV010A-10JI?
The nCASC pin on the AT17LV010A-10JI is an active-Low cascade select output that asserts Low when its internal address counter reaches the final memory location. In a daisy-chain, this signal connects directly to the nCS pin of the next AT17LV device, automatically enabling its DATA output and address counter. This hardware handshaking eliminates timing-critical software coordination and ensures glitch-free multi-device configuration, as verified in Figure 10 and Section 7 ("Cascading Serial Configuration EEPROMs").
Is the AT17LV010A-10JI pin-compatible with other devices in the AT17LV family?
Yes, the AT17LV010A-10JI shares identical pinouts with all AT17LV devices in the 20-lead PLCC package (e.g., AT17LV512A-10JI, AT17LV256A-10JI), as confirmed in Table 1 and Pin Configuration diagrams. This allows direct substitution within the same footprint for density upgrades or downgrades without PCB revision-provided voltage, timing, and feature requirements (e.g., WP1 presence) are compatible.
What is the data retention specification for the AT17LV010A-10JI at industrial temperature?
The AT17LV010A-10JI guarantees 90 years of data retention at 85°C, as stated in the "High-reliability" section of the datasheet. This value is derived from accelerated life testing and applies specifically to industrial-grade parts (suffix 'I'). It exceeds typical industrial equipment lifespans and ensures bitstream integrity without periodic refresh or backup mechanisms-even in thermally stressed enclosures.
