Product details
Overview
AT49BV1614A-70TI from Microchip Technology (formerly Atmel) is a 16-Mbit (1M × 16 / 2M × 8) 3.3V Flash memory IC with sector erase architecture, 70 ns access time, and dual-plane concurrent read/program-erase capability. It supports byte/word mode via BYTE pin, features erase suspend/resume, and targets embedded boot code storage in industrial controllers and communication modules.
For engineers reviewing the AT49BV1614A-70TI datasheet, AT49BV1614A-70TI pinout, AT49BV1614A-70TI application, or AT49BV1614A-70TI equivalent, key selection criteria include its 39-sector organization (31 × 64KB + 8 × 8KB), VPP-accelerated programming (5V/12V), 128-bit protection register, and TSOP/CBGA package compatibility for legacy system upgrades.
Technical Context
The AT49BV1614A-70TI implements a dual-plane Flash architecture: Plane A contains eight 4K-word and seven 32K-word sectors; Plane B contains twenty-four 32K-word sectors. This enables concurrent read from one plane while programming or erasing the other - eliminating wait states during firmware updates.
It uses command-based operation with six-byte sequences for chip/sector erase and lockdown, supports hardware data protection (VCC sense, noise filtering), and provides three end-of-operation detection methods: RDY/BUSY open-drain output, Data Polling on I/O7, and Toggle Bit on I/O6/I/O2 - all validated for 70 ns timing grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit or 2,097,152 × 8-bit) - supports boot code and firmware image storage in space-constrained designs |
| Access Time | 70 ns - meets real-time read latency requirements for microcontroller boot ROM interfaces |
| Supply Voltage | 2.65V to 3.3V - compatible with 3.3V logic systems and low-power embedded platforms |
| Sector Architecture | 39 sectors: 31 × 64KB + 8 × 8KB - enables granular firmware partitioning and secure bootloader isolation |
| Program/Erase Speed | 20 µs word program; 300 ms sector erase - balances update speed with reliability in field-programmable applications |
| Power Consumption | 30 mA active; 10 µA standby - suitable for battery-backed or always-on industrial control units |
| VPP Acceleration | 5.0V ± 0.5V or 12.0V ± 0.5V on VPP pin - reduces program/erase time without increasing VCC load |
Pinout & Package
AT49BV1614A-70TI is available in 48-lead TSOP (Type 1) and 48-ball CBGA packages. Pin functions are identical across both packages, with ball/pin mapping confirmed per official Microchip datasheet Rev. 1411F.

| CE, OE, WE | Chip Enable, Output Enable, Write Enable | Dual-line control (CE+OE) prevents bus contention; standard microprocessor timing compliance |
| BYTE | Mode Select | Logic "1" = x16 mode (I/O0–I/O15 active); Logic "0" = x8 mode (I/O0–I/O7 active, I/O15 = A-1) |
| RDY/BUSY | Open-drain status output | Active-low signal for hardware polling; supports OR-tying of multiple devices on shared bus |
| VPP | Accelerated Program/Erase Supply | Accepts 5V or 12V to reduce internal charge pump time; optional - may be unconnected for VCC-only operation |
| RESET | Hardware Initialization | Forces device into read/standby mode; required to exit Single Pulse Program mode |
| VCCQ | Output Driver Power | Separate 1.8–3.3V supply for I/O drivers - enables mixed-voltage I/O interfacing |
Key Features
| Feature | Design Value |
|---|---|
| Dual-plane concurrent operation | Enables real-time read from Plane B while erasing/programming Plane A - critical for zero-downtime firmware updates |
| Erase Suspend/Resume | Halts active sector erase to service urgent read/program requests in other sectors - improves system responsiveness |
| Sector Lockdown | Per-sector write-protection via six-byte command - secures boot code against accidental overwrite during field updates |
| 128-bit Protection Register | Factory-programmed 64-bit block + user-programmable/lockable 64-bit block - supports secure device authentication and licensing |
| Hardware Data Protection | VCC sense, 10 ms power-on delay, noise filtering (<15 ns), and control-line inhibit - prevents spurious writes in 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 | Single-plane architecture; no erase suspend; 48-pin TSOP only; 70 ns access, 3.0–3.6V | Lacks dual-plane concurrency and sector lockdown - requires software-managed erase sequencing | Lower-cost option where concurrent read/erase is not required and security features are handled externally |
| MX29LV160DBTI-70G | Boot-block architecture (top/bottom); 3.0–3.6V; 70 ns; no VPP pin; 48-pin TSOP | Fixed boot-block layout (16KB + 8KB + 32KB + 64KB) vs. configurable 39-sector map; no 128-bit protection register | Better suited for simple boot code storage where flexible sector sizing and hardware security are non-critical |
Compared with SST39VF1601C-70-4C-EKE and MX29LV160DBTI-70G, the AT49BV1614A-70TI uniquely delivers dual-plane concurrency, hardware-enabled sector lockdown, and VPP-accelerated programming - making it optimal for systems requiring deterministic firmware update behavior and embedded security.

FAQ
What is the operating temperature range for the AT49BV1614A-70TI?
The AT49BV1614A-70TI is rated for industrial temperature operation from –40°C to +85°C (case temperature), as specified in the DC and AC Operating Range table of the official Microchip datasheet Rev. 1411F. This makes the AT49BV1614A-70TI suitable for deployment in harsh environments such as factory automation controllers and outdoor telecom infrastructure.
Does the AT49BV1614A-70TI support both x8 and x16 data bus configurations?
Yes, the AT49BV1614A-70TI supports both configurations via the BYTE pin: when BYTE = logic "1", it operates in x16 mode with I/O0–I/O15 active; when BYTE = logic "0", it operates in x8 mode with I/O0–I/O7 active and I/O15 repurposed as LSB address input (A-1). This flexibility allows the AT49BV1614A-70TI to interface directly with 8-bit or 16-bit microcontrollers without external glue logic.
How does the erase suspend feature work in the AT49BV1614A-70TI?
The AT49BV1614A-70TI's erase suspend feature halts an ongoing sector erase operation within 15 µs, allowing immediate read or program access to any other sector in the same memory plane. It is triggered by the B0h command and requires no address. The AT49BV1614A-70TI automatically resumes erase upon receipt of the 30h resume command with plane address (A19–A18), enabling responsive multitasking in firmware update routines.
Can the AT49BV1614A-70TI be programmed using only the VCC supply, or is VPP required?
The AT49BV1614A-70TI can be fully programmed and erased using only the VCC supply (2.65V–3.3V); VPP is optional and used solely to accelerate programming and erase times. When VPP ≤ VCC or unconnected, the device defaults to VCC-powered operation. VPP must be set to 5.0V ± 0.5V or 12.0V ± 0.5V to enable acceleration - the AT49BV1614A-70TI internally selects the appropriate supply based on voltage comparison.
What is the purpose of the 128-bit protection register in the AT49BV1614A-70TI?
The AT49BV1614A-70TI's 128-bit protection register consists of two 64-bit blocks: Block A is factory-programmed with a unique identifier and cannot be altered; Block B is user-programmable and lockable. It supports secure device authentication, firmware version binding, and anti-cloning measures - accessed via Product ID Entry command and protected by dedicated Program/Lock Protection Register commands.
