Product details
Overview
AT49BV1614T-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 AT49BV1614T-11CI datasheet, AT49BV1614T-11CI pinout, AT49BV1614T-11CI application, or AT49BV1614T-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 TSOP/µBGA package compatibility for space-constrained PCB layouts.
Technical Context
The AT49BV1614T-11CI implements a dual-plane memory architecture: Plane A contains eight 4K-word, two 16K-word, and six 32K-word sectors; Plane B contains twenty-four 32K-word sectors. This enables true concurrent read while program/erase - reads from one plane proceed uninterrupted during write/erase on the other.
It features hardware-based sector protection (lockout), software-controlled erase suspend/resume, and three end-of-operation detection methods: RDY/BUSY pin, Data Polling (I/O7 complement), and Toggle Bit (I/O6 toggling). The BYTE pin selects between x16 (I/O0–I/O15 active) and x8 (I/O0–I/O7 active, I/O15 repurposed as A−1) data bus configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit or 2,097,152 × 8-bit) - supports full boot image storage in word mode or compact firmware in byte mode. |
| Access Time | 90 ns - meets timing requirements for 11 MHz bus interfaces without wait states in standard read cycles. |
| Supply Voltage | 2.7 V to 3.3 V - compatible with modern low-voltage microcontroller I/O domains and eliminates need for level shifters. |
| Program Time | 20 µs per word - enables rapid field firmware patching with minimal system downtime. |
| Sector Erase Time | 200 ms per sector - allows selective firmware module updates without full chip erase latency. |
| Standby Current | 10 µA - suitable for battery-backed or energy-sensitive applications requiring ultra-low quiescent power. |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded systems including motor drives and PLCs. |
Pinout & Package
AT49BV1614T-11CI is available in 48-lead TSOP Type 1 and 48-ball µBGA packages. Pin functions are identical across both packages; ball/lead mapping follows JEDEC MO-141 and JESD-22 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1M-word addressing; A−1 function on I/O15 in byte mode. |
| I/O0–I/O15 | Data I/O (x16) / I/O0–I/O7 + A−1 (x8) | Configurable bidirectional data bus; BYTE pin determines width and repurposes I/O15 as LSB address in byte mode. |
| CE | Chip Enable | Active-low chip select; must be low with OE low and WE high for valid read access; prevents bus contention. |
| OE | Output Enable | Active-low output control; used with CE to gate data outputs; high-Z when inactive. |
| WE | Write Enable | Active-low write strobe; latches command sequences and data during programming/erase cycles. |
| BYTE | Bus Width Select | Logic high = x16 mode (I/O0–I/O15 active); logic low = x8 mode (I/O0–I/O7 active, I/O15 = A−1). |
| RDY/BUSY | Open-drain Status Output | Actively pulled low during internal program/erase; supports wired-OR of multiple devices on shared status line. |
| RESET | Hardware Initialization | Active-low reset; halts ongoing operations and forces high-Z outputs; 12V ±0.5V override enables locked-sector reprogramming. |
| VPP | Optional Programming Supply | Accepts 4.5–5.5 V to accelerate program/erase; tied to VCC if unused; not required for basic 2.7–3.3V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-plane concurrent read/program/erase | Enables real-time firmware validation during background updates - no system stall required for read access during write operations. |
| Erase suspend/resume | Halts active sector erase within 15 µs to service urgent read or program requests in another sector - critical for deterministic response in safety-critical systems. |
| Individual sector write lockout | Permits permanent protection of boot code sectors (e.g., SA0–SA7) while allowing dynamic update of application partitions - prevents accidental corruption of startup routines. |
| Three end-of-operation detection methods | RDY/BUSY pin, Data Polling (I/O7), and Toggle Bit (I/O6) provide redundant, software- or hardware-driven cycle completion signaling - improves system robustness and debug visibility. |
| Hardware data protection | VCC sense, 10 ms power-on delay, noise filtering (<15 ns), and control-line inhibit prevent spurious writes - essential for reliable in-system programming in electrically noisy environments. |

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 | 16 Mbit, 70 ns access, 3.0–3.6 V supply, no dual-plane or erase suspend; 48-TSOP only. | Lacks concurrent read/erase and sector suspend - requires full system stall during updates. | Select when cost sensitivity outweighs real-time update needs and voltage range aligns with 3.3 V ±10% rails. |
| MX29LV160DBTI-70G | 16 Mbit, 70 ns, 3.0–3.6 V, top/bottom boot block, no dual-plane; supports CFI but no BYTE-mode flexibility. | Fixed boot-block orientation limits partitioning options; no hardware sector lockout override via RESET. | Prefer for legacy designs using standard CFI-compliant programmers where boot-block symmetry is required. |
Compared with SST39VF1601C-70-4C-EKE and MX29LV160DBTI-70G, AT49BV1614T-11CI uniquely delivers dual-plane concurrency and hardware-overrideable sector lockout - enabling safer, faster, and more flexible firmware management in real-time embedded systems.

FAQ
What is the difference between AT49BV1614T-11CI and AT49BV1604T-11CI?
The AT49BV1614T-11CI and AT49BV1604T-11CI share identical electrical specifications and pinout but differ in sector mapping: AT49BV1614T-11CI allocates smaller sectors (eight 4K-word, two 16K-word, thirty 32K-word) in Plane A and larger uniform sectors in Plane B, whereas AT49BV1604T-11CI reverses this distribution. This affects boot code placement and update granularity - AT49BV1614T-11CI better supports modular firmware with protected small boot sectors.
Does AT49BV1614T-11CI support both x8 and x16 data bus modes?
Yes, AT49BV1614T-11CI supports both modes via the BYTE pin: logic high enables x16 operation (I/O0–I/O15 active), logic low enables x8 operation (I/O0–I/O7 active, I/O15 functions as A−1 address input). This flexibility allows seamless integration with 8-bit or 16-bit microcontrollers without external glue logic.
How does the erase suspend feature work in AT49BV1614T-11CI?
AT49BV1614T-11CI's erase suspend halts an active sector erase within 15 µs upon receipt of the B0H command, allowing immediate read or program access to any other sector in the same memory plane. Resume uses a 30H command with plane address (A18/A19). This avoids system stalls during critical foreground tasks - a key advantage over single-plane Flash devices.
Can AT49BV1614T-11CI be programmed using only a 3.3V supply?
Yes, AT49BV1614T-11CI operates fully with a single 2.7–3.3V supply for read, program, and erase. The VPP pin is optional: applying 4.5–5.5V reduces program/erase times but is not required. All command sequences, including sector lockout and erase, function correctly at 3.3V nominal.
What packaging options are available for AT49BV1614T-11CI?
AT49BV1614T-11CI is offered in two RoHS-compliant packages: 48-lead TSOP Type 1 (standard surface-mount) and 48-ball µBGA (10 mm × 12 mm, 0.8 mm pitch). Both share identical pin functions and timing; the µBGA variant supports higher board density in space-constrained applications like portable medical devices.
