Product details
Overview
AT49BV6416-70TI from Microchip Technology is a 64-megabit (4M × 16) parallel-interface Flash memory IC operating from 2.7V to 3.6V, featuring 70 ns asynchronous access time and TSOP-48 packaging. It implements four-plane architecture with sector erase, suspend/resume capability, and Common Flash Interface (CFI) for system-level configuration. Used in embedded firmware storage, boot code retention, and industrial controller nonvolatile memory.
For engineers reviewing the AT49BV6416-70TI datasheet, AT49BV6416-70TI pinout, AT49BV6416-70TI application, or AT49BV6416-70TI equivalent, key selection criteria include 70 ns read timing, 4M×16 organization, TSOP-48 footprint compatibility, sector protection modes (Softlock/Hardlock), and VPP-assisted accelerated programming at 10 V.
Technical Context
The AT49BV6416-70TI uses a four-plane memory architecture enabling concurrent reads across three planes while one plane undergoes program or erase. Each plane holds 16 Mbit, with dedicated 4K-word and 32K-word sector layouts supporting independent write lockout.
It supports dual operational modes: standard asynchronous read (70 ns) and page read (20 ns for subsequent words within 4-word pages). Erase and program operations are managed via command sequences using CE/OE/WE control lines and address latching on falling edges, with status monitored via I/O5–I/O7 polling and toggle bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4M × 16 organization), providing 8 MB of nonvolatile storage space |
| Access Time | 70 ns max asynchronous read - defines minimum bus cycle time for random access |
| Page Read Speed | 20 ns per word after first access - enables burst-like throughput within 4-word pages |
| Voltage Range | 2.7V–3.6V core supply; VCCQ supports 2.2V–3.6V I/O voltage - allows low-power interface design |
| Sector Architecture | Eight 4K-word top/bottom boot sectors + 127 × 32K-word main sectors - enables granular firmware partitioning |
| Erase Times | 700 ms typical for 32K-word sectors; 200 ms for 4K-word sectors - impacts firmware update latency |
| Power Consumption | 30 mA active current; 35 µA standby - suitable for battery-backed or low-duty-cycle systems |
Pinout & Package
AT49BV6416-70TI is housed in a 48-pin Thin Small Outline Package (TSOP Type I, 12 × 20 mm), compliant with JEDEC MO-141BA. Pin assignments follow industry-standard parallel Flash interface layout with separate VCCQ for I/O voltage control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O0–I/O15 | Data Inputs/Outputs | 16-bit bidirectional data bus; VCCQ-referenced outputs support 2.2V–3.6V logic levels |
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A0–A1 used for page mode toggling |
| CE | Chip Enable | Active-low chip select; must be low with OE low and WE high for read access |
| OE | Output Enable | Active-low output control; used with CE to prevent bus contention during read |
| WE | Write Enable | Active-low write strobe; latches addresses/data during command sequences and programming |
| RESET | Device Reset | Active-low hardware reset; halts ongoing operations and forces high-impedance outputs |
| WP | Write Protect Input | Hardware-enables Hardlock sector protection when low; overrides software unlock if Hardlock is set |
| VPP | Program Voltage Supply | Enables accelerated dual-word programming at 10 V; inhibits program/erase below 0.7 V |
| VCCQ | I/O Power Supply | Separate 2.2V–3.6V supply for data pins - decouples I/O voltage from core VCC |
| VCC | Core Power Supply | 2.7V–3.6V supply for internal logic and memory array; includes VCC sense for power-on safety |
| GND | Ground Reference | Dual ground pins (pins 24 and 47) minimize noise coupling in high-speed parallel operation |
Key Features
| Feature | Design Value |
|---|---|
| Four-plane concurrent read | Enables real-time read access from any three planes while fourth is being programmed or erased - eliminates read stalls during updates |
| Erase/program suspend/resume | Allows interruption of long-duration operations (≤700 ms) to service urgent reads or writes - improves system responsiveness |
| Softlock/Hardlock sector protection | Two independent software/hardware locking modes per sector - supports mixed firmware (static boot vs. dynamic app) security models |
| 128-bit user-programmable protection register | Factory-block A + user-lockable block B - enables secure device identification and anti-cloning in production systems |
| Common Flash Interface (CFI) | Standardized query mode (0x98 at 0x55) returns timing, geometry, and command-set parameters - simplifies driver portability across Flash vendors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF6401B-70-4C-EKE | 64 Mbit (4M × 16), 70 ns access, 3.0V–3.6V only, no VPP pin, lacks suspend/resume | No erase/program suspend capability; simpler command set but no concurrent plane reads | Choose when VPP complexity and suspend features are unnecessary and 2.7V operation is not required |
| MX29LV640ETTI-70G | 64 Mbit (4M × 16), 70 ns, 2.7V–3.6V, supports CFI and sector protection, but no four-plane architecture | Lacks concurrent multi-plane read; single-plane design limits read-throughput during program/erase | Prefer when board layout requires pin-compatible replacement but multi-plane performance is secondary |
Compared with SST39VF6401B-70-4C-EKE and MX29LV640ETTI-70G, the AT49BV6416-70TI uniquely delivers four-plane concurrent read and full suspend/resume functionality - critical for systems requiring uninterrupted data access during firmware updates or field reprogramming.

FAQ
What is the maximum operating temperature range for the AT49BV6416-70TI?
The AT49BV6416-70TI is rated for operation from –40°C to +85°C under bias conditions, meeting industrial temperature requirements. Its absolute maximum junction temperature is +125°C, but sustained operation above +85°C may impact data retention and endurance specifications. The device incorporates VCC sense circuitry that disables programming below 1.8 V, enhancing thermal safety during power-up sequences. Always verify thermal derating in your PCB layout when operating near upper limits.
Does the AT49BV6416-70TI support true 2.7V-only operation for both read and program functions?
Yes, the AT49BV6416-70TI fully supports 2.7V–3.6V operation for all functions including read, program, and erase. Its VCC sense circuitry ensures program inhibition below 1.8 V (typical), and internal timing generators are calibrated across the full 2.7V–3.6V range. However, accelerated dual-word programming requires VPP = 10 V, which is independent of VCC level. For standard single-word programming at 2.7V, the AT49BV6416-70TI remains fully functional without external voltage boosting.
How does the four-plane architecture of the AT49BV6416-70TI improve system performance compared to single-plane Flash?
The AT49BV6416-70TI's four-plane architecture allows reads to occur concurrently in any three planes while the fourth plane executes program or erase - eliminating wait states during firmware updates. This contrasts with single-plane Flash like the MX29LV640ETTI-70G, where all reads stall during erase. In practice, this enables real-time data logging or UI rendering during background firmware patches, reducing system latency by up to 700 ms per sector update. Plane addressing uses A21–A20 bits, requiring no additional control signals.
Can the AT49BV6416-70TI be used as a direct replacement for the AT49BV6416T variant?
Yes, the AT49BV6416-70TI and AT49BV6416T share identical electrical specifications, pinout, command set, and timing - differing only in temperature grade (Industrial vs. Commercial) and screening. Both use TSOP-48 packaging, support 70 ns access, and implement the same four-plane architecture and CFI structure. No PCB or firmware changes are needed for substitution, though the -70TI's extended temperature range makes it suitable for harsher environments where the -70T is not rated.
What is the role of the VPP pin on the AT49BV6416-70TI beyond write protection?
Beyond enabling write protection when held below 0.7 V, the VPP pin on the AT49BV6416-70TI provides 10 V for accelerated dual-word programming - reducing write time per word pair by up to 40% versus standard 2.7V–3.6V operation. It also serves as a status input: the I/O3 pin reflects VPP voltage level during program/erase, allowing software to detect insufficient programming voltage before initiating commands. This dual-role design eliminates need for external voltage supervisors in many applications.
