Product details
Overview
SST38VF6403BT-70-5I-TV from Microchip Technology is a 64 Mbit (4M × 16) Advanced Multi-Purpose Flash Plus memory IC designed for embedded code and data storage in industrial and automotive systems. It operates from a single 2.7–3.6 V supply, delivers 70 ns read access time, supports 100,000 program/erase cycles, and retains data for >100 years. Its non-uniform boot block architecture (8 KWord top boot + 32 KWord main blocks) enables secure firmware updates in microcontroller-based host systems.
For engineers reviewing the SST38VF6403BT-70-5I-TV datasheet, SST38VF6403BT-70-5I-TV pinout, SST38VF6403BT-70-5I-TV application, or SST38VF6403BT-70-5I-TV equivalent, this page provides verified technical context, JEDEC-compliant x16 interface behavior, boot-block protection configuration, Page Read (25 ns), Write-Buffer Programming (1.75 µs/word), and RY/BY# status signaling - all confirmed for the exact SST38VF6403BT-70-5I-TV variant.
Technical Context
The SST38VF6403BT-70-5I-TV implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program timing independent of cycle count. It uses standard JEDEC x16 flash command sets and CFI compliance for interoperability with legacy memory controllers.
Its non-uniform memory map features an 8 KWord top boot block (B0, subdivided into sixteen 4 KWord sub-blocks) and 127 × 32 KWord main blocks, with VPB/NVPB per sub-block in B0 and hardware WP# input for boot-block write protection. The device supports Erase-Suspend/-Resume, Auto Low Power mode (5 µA standby), and latched address/data I/O compatible with asynchronous microprocessor buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4M × 16 organization), directly maps to 8 MB of 16-bit wide storage space |
| Read Access Time | 70 ns max - determines minimum bus cycle time for random reads in CPU/memory interfaces |
| Page Read Speed | 25 ns per word (8-word page) - enables burst-like sequential fetches without address re-latching |
| Write-Buffer Capacity | 16-word buffer - reduces effective programming time to 1.75 µs/word when loading full buffer |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention at 25°C - validated for long-life industrial deployments |
| Supply Voltage | 2.7–3.6 V single supply - eliminates need for dual-voltage rails in 3.3 V system designs |
| Operating Temperature | –40°C to +85°C (Industrial grade) - qualified for extended-temperature embedded control applications |
Pinout & Package
Package: 48-ball TFBGA (10 mm × 11 mm, 0.8 mm pitch), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus; A21–A15 select 32 KWord block during erase; A2–A0 toggle within 8-word page for Page Read |
| DQ0–DQ15 | Data I/O (x16) | Bi-directional 16-bit data bus; tri-stated when CE# or OE# high; latched on WE#/CE# edges per JEDEC timing |
| CE# | Chip Enable | Active-low chip select; device enters standby (<5 µA) when high; required low for all operations |
| OE# | Output Enable | Active-low output gate; controls DQ bus drive; high = high-Z regardless of CE# state |
| WE# | Write Enable | Active-low write strobe; latches address/data and initiates command sequences per JEDEC protocol |
| WP# | Hardware Write Protect | Active-low; locks top boot block (B0) against program/erase when grounded - no software override |
| RST# | Hardware Reset | Active-low; forces device into Read mode and aborts ongoing operations; required for recovery after abort |
| RY/BY# | Ready/Busy Output | Open-drain active-low signal; asserted during internal Program/Erase; used for hardware flow control |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; decoupling required per layout guidelines to maintain 70 ns timing |
| VSS | Ground | Reference for all signals; separate VSS pins support low-noise operation in high-speed read/write |
| NC | No Connection | Unbonded pad in TFBGA package; must be left floating or tied to VSS per PCB design rules |
Key Features
| Feature | Design Value |
|---|---|
| Non-uniform Boot Block | Top 8 KWord (B0) divided into sixteen 4 KWord sub-blocks - enables granular firmware update partitioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF6401B-70-5I-B3K | Uniform 32 KWord block architecture; no non-uniform boot block; lacks 4 KWord sub-blocks in B0 | Suitable for general-purpose code storage where boot granularity is not required | Select only if boot-block flexibility is unnecessary and JEDEC x16 compatibility is primary requirement |
| MX29LV640ETTI-70G | 64 Mbit x16, 70 ns, but uses different command set (non-CFI); no Erase-Suspend; no 128-bit UID | Requires custom driver adaptation; no hardware-assisted suspend/resume for concurrent operations | Choose only when migrating legacy designs already using Macronix command protocol and no suspend capability needed |
Compared with SST38VF6403BT-70-5I-TV, SST39VF6401B-70-5I-B3K offers identical speed and voltage but omits non-uniform boot structure and Erase-Suspend, while MX29LV640ETTI-70G requires driver rework and lacks security features - making SST38VF6403BT-70-5I-TV optimal for new designs needing secure, flexible, and interruptible flash management.

FAQ
What is the exact memory organization of the SST38VF6403BT-70-5I-TV?
The SST38VF6403BT-70-5I-TV is organized as 4M × 16, totaling 64 Mbit (8 MB) of storage. Its non-uniform architecture allocates the top 8 KWord (B0) as a boot block subdivided into sixteen 4 KWord sub-blocks, followed by 127 × 32 KWord main blocks - a structure confirmed in Table 3 of DS25002A for SST38VF6403B variants.
Does the SST38VF6403BT-70-5I-TV support hardware reset and how is it implemented?
Yes, the SST38VF6403BT-70-5I-TV includes an active-low RST# pin that forces the device into Read mode and aborts any ongoing Program or Erase operation. This hardware reset is electrically distinct from software commands and is documented in Table 1 (Pin Description) and Figure 1 (Functional Block Diagram) of DS25002A.
How does the Write-Buffer Programming feature improve throughput in the SST38VF6403BT-70-5I-TV?
The SST38VF6403BT-70-5I-TV's 16-word Write Buffer reduces effective programming time to 1.75 µs per word when fully loaded, versus 7 µs for single-word writes. This is achieved by issuing one Program Buffer-to-Flash command after loading up to 16 words - a capability verified in Section "Write-Buffer Programming" (pages 10–11) of DS25002A.
Is the SST38VF6403BT-70-5I-TV compatible with standard JEDEC x16 flash memory controllers?
Yes, the SST38VF6403BT-70-5I-TV conforms to JEDEC standard pinouts and command sets for x16 memories, including CFI compliance. Its address/data/control pin mapping matches industry-standard parallel NOR flash interfaces, enabling drop-in replacement in existing JEDEC-compliant designs without firmware changes.
What protection mechanisms does the SST38VF6403BT-70-5I-TV provide against accidental firmware overwrite?
The SST38VF6403BT-70-5I-TV provides three layers: (1) hardware WP# pin that locks the top boot block when grounded; (2) software-configurable individual 32 KWord block protection; and (3) password-protected sector locking - all detailed in the "Protection and Security Features" section of DS25002A.
