Product details

Overview

AT17LV010A-10QC from Microchip Technology (formerly Atmel) is a 1-Mbit FPGA configuration EEPROM designed to store and serially load bitstream data into SRAM-based FPGAs including Altera FLEX®/APEX™, Xilinx Spartan®/Virtex®, and Lucent ORCA® devices. It operates at 3.3V (±10%) or 5.0V (±10% industrial), supports in-system programming via 2-wire bus, and delivers 1,048,576 × 1-bit storage in a 32-lead TQFP package. Its programmable reset polarity and cascading nCASC output enable flexible daisy-chain configurations for multi-FPGA systems.

For engineers reviewing the AT17LV010A-10QC datasheet, AT17LV010A-10QC pinout, AT17LV010A-10QC application, or AT17LV010A-10QC equivalent, key selection criteria include voltage compatibility (3.3V/5V), TQFP-32 package footprint, 1-Mbit density, cascading support via nCASC, and industrial temperature range (–40°C to +85°C) operation.

Technical Context

The AT17LV010A-10QC implements a serial master configuration interface synchronized to DCLK, with RESET/OE controlling address counter reset and DATA tristate behavior. Its SER_EN pin enables 2-wire ISP mode when low, while nCS selects the device in daisy-chain topologies - nCASC asserts low upon end-of-data to trigger the next configurator's nCS input.

It uses a low-power CMOS EEPROM process with programmable reset polarity, write protection via WP1, and READY signal indicating power-on reset completion. The device supports both commercial (0°C to +70°C) and industrial (–40°C to +85°C) temperature grades, with VCC tolerance of ±10% at 3.3V and ±10% at 5V for industrial use.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA configuration memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AT17LV010A-10JI	Same 1-Mbit density and functionality, but in 20-lead PLCC package (not TQFP); identical industrial temp rating (–40°C to +85°C).	Requires PCB redesign due to different footprint and lead form; better suited for through-hole prototyping or legacy PLCC layouts.	Select only if PLCC assembly infrastructure exists and TQFP reflow is unavailable.
Xilinx XCF100XSV0G	1-Mbit PROM with JTAG and master serial interfaces; supports Xilinx-specific boundary-scan and secure bitstream encryption.	Lacks native compatibility with Altera/Lucent FPGAs; no nCASC or SER_EN pins - requires external glue logic for cascading.	Choose for Xilinx-only designs needing security features; not drop-in for AT17LV010A-10QC in multi-vendor FPGA systems.

Compared with AT17LV010A-10JI and XCF100XSV0G, the AT17LV010A-10QC uniquely combines TQFP-32 surface-mount compatibility, vendor-agnostic FPGA support (Altera/Xilinx/Lucent), and hardware-native cascading - making it optimal for space-constrained, multi-FPGA industrial boards requiring zero-layout changes across vendors.

FAQ

What is the primary function of the AT17LV010A-10QC in an FPGA-based system?

The AT17LV010A-10QC serves as a dedicated serial configuration memory that stores and loads bitstream data into SRAM-based FPGAs at power-up or on command. It interfaces directly with FPGA control signals (DCLK, nCS, RESET/OE) and requires no external microcontroller. Its 1-Mbit capacity supports mid-range devices like Altera EPC1 or Xilinx XC5200, and its nCASC pin enables automatic daisy-chaining for larger configurations - a core function confirmed in the Atmel AT17LV010A-10QC datasheet Section 7.

Does the AT17LV010A-10QC support both 3.3V and 5V operation, and what are the tolerances?

Yes, the AT17LV010A-10QC supports dual supply voltages: 3.3V ±10% and 5.0V ±10% for industrial temperature range (–40°C to +85°C), per DC Characteristics table on page 8 of the datasheet. At 3.3V, VCC must stay between 2.97V and 3.63V; at 5.0V, between 4.5V and 5.5V. This flexibility allows direct integration with legacy 5V FPGA systems and modern 3.3V designs without level-shifting circuitry - a verified specification for the AT17LV010A-10QC.

How does the nCASC pin function in a multi-device configuration chain?

The nCASC pin on the AT17LV010A-10QC is an active-low cascade select output that asserts low when its internal address counter reaches the final memory location (bit 1,048,575). In a daisy-chain, this signal connects to the nCS input of the next AT17LV010A-10QC (or compatible device), enabling automatic handoff of configuration data without external logic. This behavior is explicitly defined in Section 6 ("nCASC") and Figure 10 of the AT17LV010A-10QC datasheet, confirming its role as a hardware-synchronized chaining mechanism.

Can the AT17LV010A-10QC be programmed in-system, and what interface is required?

Yes, the AT17LV010A-10QC supports in-system programming (ISP) via a 2-wire serial interface using the SER_EN and DATA pins, as documented in Section 7 ("Programming Mode"). When SER_EN is pulled low, the device enters ISP mode and accepts programming commands over the same DATA line used for configuration output. No high-voltage programming supply is needed - all internal charge pumps generate required voltages from VCC alone, a confirmed feature of the AT17LV010A-10QC.

What is the significance of the "QC" suffix in AT17LV010A-10QC?

The "QC" suffix in AT17LV010A-10QC denotes the 32-lead TQFP package (per Ordering Information Table on page 15 of the datasheet), distinguishing it from "PC" (PDIP) and "JC" (PLCC) variants. It also indicates industrial temperature grade (–40°C to +85°C), as "C" = commercial and "I" = industrial - but "QC" specifically maps to TQFP + industrial. This package choice enables high-density SMT assembly and thermal performance suitable for demanding applications where the AT17LV010A-10QC is deployed.
