Product details
Overview
AT17LV010-10JC from Atmel is a 1-Mbit (1,048,576 × 1-bit) serial EEPROM FPGA configuration memory supporting both 3.3V and 5.0V operation, featuring in-system programmability via two-wire bus, programmable reset polarity, and cascading capability via CEO output. It targets SRAM-based FPGAs including Xilinx XC4000/XC5200/Spartan, Altera FLEX/APEX, and Atmel AT40K/AT94K devices.
For engineers reviewing the AT17LV010-10JC datasheet, AT17LV010-10JC pinout, AT17LV010-10JC application, or AT17LV010-10JC equivalent, key selection criteria include industrial temperature range (−40°C to +85°C), 20-lead PLCC package compatibility, CEO-driven daisy-chain support, low-power standby current (100 µA industrial), and verified interoperability with master serial mode FPGAs.
Technical Context
The AT17LV010-10JC implements a serial configuration interface where CLK increments an internal address counter, DATA provides open-collector bi-directional I/O for programming and read-out, and RESET/OE serves dual function as active-low reset and active-high output enable. SER_EN must be held high during FPGA loading and pulled low only for ISP.
It supports cascaded configurations via CEO output-driven low upon reaching end-of-memory-to automatically enable the next device's CE input. The device uses a CMOS EEPROM process with programmable reset polarity stored in four EEPROM bytes, and includes write-protection inputs WP1 and WP2 (both present on AT17LV010).

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Xilinx XC18V01 | 1-Mbit serial PROM; single 3.3 V supply only; no 5 V support; no WP1/WP2; no programmable reset polarity | Limited to Xilinx-only ecosystems; lacks industrial temp support in standard variants; no cascading CEO | Select when designing exclusively for Xilinx platforms with strict 3.3 V rail and no requirement for field reprogramming or multi-vendor FPGA support |
| Microchip (Atmel) AT17LV002-10JC | 2-Mbit capacity; identical pinout, package, and interface; higher standby current (150 µA industrial); same WP1/WP2 and CEO features | Used where future FPGA bitstream growth is anticipated or dual-FPGA configurations require more than 1 Mbit | Select when board layout must remain unchanged but memory headroom is needed; drop-in upgrade path with no schematic changes |
Compared with XC18V01 and AT17LV002-10JC, the AT17LV010-10JC uniquely balances 5 V compatibility, industrial temperature rating, dual write-protect, and cascading CEO-making it optimal for mixed-voltage, multi-FPGA, and long-lifecycle industrial deployments.

FAQ
What is the operating voltage range supported by the AT17LV010-10JC?
The AT17LV010-10JC supports dual-voltage operation: 3.3 V ±10% and 5.0 V ±10% over the industrial temperature range (−40°C to +85°C). This allows direct integration into legacy 5 V systems and modern 3.3 V FPGA designs without level-shifting circuitry. DC characteristics are separately specified for each voltage, with distinct VIH/VIL thresholds and current consumption values.
Does the AT17LV010-10JC support daisy-chaining with other configuration memories?
Yes, the AT17LV010-10JC supports hardware daisy-chaining via its CEO (Chip Enable Output) pin, which asserts low upon completion of its internal memory read. This signal can directly drive the CE input of the next AT17LV device in the chain. The feature is explicitly confirmed for AT17LV512/010/002 devices and is used in documented cascaded configurations with identical timing behavior.
What package type is used for the AT17LV010-10JC, and is it compatible with other AT17LV variants?
The AT17LV010-10JC uses a 20-lead PLCC (Plastic Leaded Chip Carrier) package (JEDEC MS-018, 20J). It shares this package option with AT17LV512-10JC and AT17LV002-10JC, and all three share identical pinouts per Table 1-1 and Figure 2-4. However, AT17LV65/128/256 use different pinouts and are not pin-compatible.
How is in-system programming (ISP) performed on the AT17LV010-10JC?
ISP is enabled by pulling SER_EN low, placing the AT17LV010-10JC into two-wire serial programming mode. Programming occurs at the same VCC supply voltage (3.3 V or 5 V); no external high-voltage programming signal is required. Internal charge pumps generate necessary programming voltages. Industry-standard programmers-including Atmel's ATDH2225 ISP Cable-are fully compatible.
What is the data retention specification for the AT17LV010-10JC at industrial temperature?
The AT17LV010-10JC guarantees 90 years of data retention at 85°C (industrial grade), as explicitly stated in the "High-reliability" section of the datasheet. This value is measured and validated-not extrapolated-and applies to the full 1-Mbit memory array under continuous operation at maximum rated temperature and voltage.
