Product details
Overview
AT49BV1614-11CI from Microchip Technology (formerly Atmel) is a 16-Mbit (1M × 16 / 2M × 8) 2.7–3.3V Flash memory IC with dual-plane architecture, 90 ns access time, and sector erase capability across 40 independently lockable sectors. It supports concurrent read-while-program/erase operations and is used in embedded boot code storage, firmware update modules, and industrial controller nonvolatile memory subsystems.
For engineers reviewing the AT49BV1614-11CI datasheet, AT49BV1614-11CI pinout, AT49BV1614-11CI application, or AT49BV1614-11CI equivalent, key selection criteria include its 2.7–3.3V single-supply operation, byte/word mode select via BYTE pin, erase suspend/resume functionality, and support for hardware reset-based sector lockout override at 12V ± 0.5V.
Technical Context
This device implements a dual-plane Flash architecture: Plane A contains eight 4K-word, two 16K-word, and six 32K-word sectors; Plane B contains twenty-four 32K-word sectors. Reads from one plane are fully permitted during program or erase operations on the other plane - enabling true background execution without bus arbitration delays.
It features hardware-based sector protection with lockout detection via software identification mode, erase suspend/resume commands (B0H/30H), and three end-of-operation detection methods: RDY/BUSY pin, Data Polling (I/O7 complement), and Toggle Bit (I/O6 and I/O2). The VPP pin supports optional 4.5–5.5V fast programming when enabled.

Key Features
| Feature | Design Value |
|---|---|
| Dual-plane concurrent operation | Enables real-time read access from one memory plane while programming/erasing the other - eliminates system stall during firmware updates |
| Erase suspend/resume | Halts ongoing sector erase (≤15 µs latency) to allow immediate read/program of other sectors - critical for responsive HMI or diagnostic logging |
| Hardware sector lockout | Prevents accidental overwrite of boot code or calibration data; lock status detectable via software ID mode at address 00002H |
| Bypass unlock command | Six-byte sequence (5555h/AAh → 2AAAh/55h → 5555h/A0h) enables single-pulse programming - accelerates production programming throughput |
| Triple end-of-operation detection | RDY/BUSY pin, Data Polling (I/O7), and Toggle Bit (I/O6/I/O2) provide redundant, software- and hardware-compatible completion signaling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4C-EKE | 70 ns access time; 3.0–3.6V supply; no VPP pin; lacks erase suspend | Higher speed but narrower voltage range; unsuitable where 2.7V brownout tolerance or suspend-resume is required | Select when maximum read performance is prioritized over low-voltage operation and advanced erase control |
| MX29LV160DBTI-70G | 70 ns access; 2.7–3.6V; top/bottom boot configuration; no dual-plane concurrency | Boot-block organization optimized for x86 BIOS; lacks concurrent read-while-erase capability | Choose for legacy PC-compatible designs requiring standard boot-sector layout and proven BIOS compatibility |
Compared with SST39VF1601C-70-4C-EKE and MX29LV160DBTI-70G, AT49BV1614-11CI uniquely delivers 2.7V operation, dual-plane concurrency, and erase suspend - making it optimal for real-time embedded systems requiring guaranteed responsiveness during firmware maintenance.

FAQ
What is the operating voltage range for AT49BV1614-11CI?
The AT49BV1614-11CI operates from 2.7V to 3.3V on VCC, with VCCQ supporting 2.7–3.6V for I/O output level control. This 2.7V minimum enables reliable operation during brownout conditions in industrial power supplies, and the separate VCCQ rail allows interfacing with mixed-voltage logic families without external level shifters - a key design advantage over many competing Flash devices.
How does the BYTE pin affect AT49BV1614-11CI operation?
The BYTE pin on AT49BV1614-11CI selects between word mode (BYTE = high, I/O0–I/O15 active) and byte mode (BYTE = low, I/O0–I/O7 active, I/O15 functions as A-1 address input). This dual-mode capability allows the same AT49BV1614-11CI device to serve both 16-bit microcontrollers and 8-bit legacy systems - reducing BOM complexity and enabling reuse across platform generations.
Can AT49BV1614-11CI perform reads during erase or program operations?
Yes - AT49BV1614-11CI supports true concurrent read-while-write/erase due to its dual-plane architecture. Reads from Plane B can occur simultaneously with program or erase operations in Plane A, and vice versa. This eliminates CPU idle time during firmware updates, directly improving system throughput in applications like network equipment and industrial HMIs where responsiveness is critical.
What is the purpose of the VPP pin on AT49BV1614-11CI?
The VPP pin on AT49BV1614-11CI accepts 4.5–5.5V to accelerate internal program and erase operations. When supplied, it reduces byte/word program time and sector erase time versus using VCC alone. If unused, VPP may be tied to VCC. This optional high-voltage path provides design flexibility: systems needing fastest programming (e.g., factory test) can use VPP, while field-deployed units may omit it for simplicity and cost savings - all without changing the AT49BV1614-11CI part number.
How is sector protection implemented in AT49BV1614-11CI?
AT49BV1614-11CI implements per-sector hardware lockout via a six-command sequence (5555h/AAh → 2AAAh/55h → 5555h/40h) to each target sector. Once enabled, protected sectors resist erasure or programming at standard VCC levels. Lockout status is readable in software ID mode at address 00002H (I/O0 = high if locked). A 12V ± 0.5V pulse on RESET overrides protection - enabling secure service reflash while preserving integrity during normal operation.
