Product details
Overview
SST38VF6404BT-70I/CD from Microchip Technology is a 64 Mbit (4M × 16) CMOS Advanced Multi-Purpose Flash Plus memory IC, designed for nonvolatile program, configuration, and data storage in embedded systems. It operates from 2.7–3.6 V, delivers 70 ns read access time, supports 100,000 erase/write cycles, and retains data for >100 years - enabling reliable firmware storage in industrial controllers and network boot loaders.
For engineers reviewing the SST38VF6404BT-70I/CD datasheet, SST38VF6404BT-70I/CD pinout, SST38VF6404BT-70I/CD application, or SST38VF6404BT-70I/CD equivalent, key selection criteria include its 48-lead TSOP package, uniform 32 KWord block architecture with boot-block protection, Write-Buffer Programming (1.75 μs/word), and JEDEC-compliant x16 interface for microprocessor-based host systems.
Technical Context
The SST38VF6404BT-70I/CD implements SuperFlash split-gate cell technology with thick-oxide tunneling injector, delivering fixed erase/program times independent of cycle count. Its command-set architecture uses standard WE#/CE#/OE# control with software data protection, RY/BY# status signaling, and hardware WP# and RST# pins for robust system-level memory management.
It supports three primary operational modes: single-word Read (70 ns), Page Read (25 ns per word, 8-word buffer), and Word-Program (7 μs typical) or Write-Buffer Programming (16-word buffer, 1.75 μs/word). Block-Erase (18 ms) and Chip-Erase (40 ms) are supported with Erase-Suspend/Resume capability for real-time interruptible updates.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF6402B-70-4C-EKE | Same 64 Mbit x16 organization, 70 ns access, but uniform 32 KWord block architecture (no 4 KWord boot sub-blocks); lacks RST# pin | Suitable for general-purpose firmware storage where boot-block granularity is not required; no hardware reset recovery path | Select if boot-block flexibility is unnecessary and RST# is unused in target design |
| MX29LV640ETTI-70G | 64 Mbit x16, 70 ns, but uses standard CFI command set without Write-Buffer Programming; slower word-program (10 μs) and no Erase-Suspend | Better suited for cost-sensitive consumer electronics where firmware update frequency and real-time interrupt handling are low priority | Choose only when SuperFlash advantages (speed, suspend, endurance) are not design-critical |
Compared with SST38VF6404BT-70I/CD, SST39VF6402B-70-4C-EKE omits boot-block subdivision and RST#, while MX29LV640ETTI-70G lacks Write-Buffer acceleration and Erase-Suspend - making SST38VF6404BT-70I/CD uniquely suited for safety-critical, field-upgradable embedded systems demanding both speed and reliability.

FAQ
What is the memory organization and voltage range of the SST38VF6404BT-70I/CD?
The SST38VF6404BT-70I/CD is organized as 4M × 16 (64 Mbit) and operates from 2.7 V to 3.6 V. This single-supply range aligns with standard 3.3 V logic systems and eliminates need for auxiliary voltage regulators. Its 4M × 16 structure provides 8 MB of directly addressable storage space, supporting full firmware images for mid-tier microcontrollers without external memory expansion.
Does the SST38VF6404BT-70I/CD support hardware reset and write protection?
Yes, the SST38VF6404BT-70I/CD includes dedicated RST# (active-low reset) and WP# (write protect) pins. RST# forces the device into Read mode upon assertion, enabling firmware recovery after power glitches or initialization errors. WP# provides hardware-level protection for boot blocks when grounded - a critical safeguard against accidental firmware corruption during field updates or debug sessions involving the SST38VF6404BT-70I/CD.
How does Write-Buffer Programming improve performance in the SST38VF6404BT-70I/CD?
Write-Buffer Programming in the SST38VF6404BT-70I/CD allows up to 16 words to be loaded into an internal buffer before committing to flash, achieving 1.75 μs per word versus 7 μs for standard Word-Program. This reduces effective programming time by over 75%, accelerating firmware patches, calibration updates, and configuration writes - especially valuable in systems where downtime during memory updates must be minimized using the SST38VF6404BT-70I/CD.
What package type and pin count does the SST38VF6404BT-70I/CD use?
The SST38VF6404BT-70I/CD is supplied in a 48-lead TSOP (Thin Small Outline Package), with JEDEC-standard pinout for x16 memories. This surface-mount package supports automated PCB assembly and offers thermal and mechanical reliability for industrial applications. Pin assignments match industry-standard flash controllers, enabling direct integration without adapter logic or footprint redesign when migrating to the SST38VF6404BT-70I/CD.
Is the SST38VF6404BT-70I/CD compliant with industry standards and environmental regulations?
Yes, the SST38VF6404BT-70I/CD is JEDEC-standard compliant for x16 flash pinouts and command sets, and fully CFI-compliant for standardized identification and interrogation. All variants are RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU. Its 100,000-cycle endurance and >100-year data retention are tested per AEC-Q100 stress conditions, qualifying it for extended-life industrial and automotive applications using the SST38VF6404BT-70I/CD.
