Product details
Overview
SST38VF6404BT-70-5I-TV from Microchip Technology is a 64 Mbit (4M × 16) CMOS Advanced Multi-Purpose Flash Plus memory IC, designed for nonvolatile program/data storage in embedded systems. It operates at 2.7–3.6 V, delivers 70 ns read access time, supports 100,000 erase/program cycles, and features hardware boot block protection with WP# pin and RY/BY# status output - used in industrial controllers requiring field-upgradable firmware.
For engineers reviewing the SST38VF6404BT-70-5I-TV datasheet, SST38VF6404BT-70-5I-TV pinout, SST38VF6404BT-70-5I-TV application, or SST38VF6404BT-70-5I-TV equivalent, key selection considerations include uniform 32 KWord block architecture, 4 KWord boot block granularity at top address range, Write-Buffer Programming (1.75 μs/word), Erase-Suspend capability, and TSOP-48 package compatibility with legacy x16 parallel interface designs.
Technical Context
This device implements SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count - unlike conventional flash where timing degrades over endurance life. Its command-set conforms to JEDEC standard x16 pinouts and CFI, supporting software-controlled individual block (32 KWord) protection and password-based security.
The SST38VF6404BT-70-5I-TV integrates latched address/data paths, auto low-power mode (5 μA standby), and dual status reporting via RY/BY# pin plus DQ6/DQ7 polling - enabling deterministic timing control in real-time firmware update sequences without external timing margining.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4M × 16), directly maps to 8 MB of byte-addressable space in x16 bus systems |
| Read Access Time | 70 ns - determines minimum CPU wait-state insertion for synchronous parallel bus interfacing |
| Page Read Speed | 25 ns per word (8-word buffer) - enables burst reads at up to 40 MB/s effective throughput |
| Endurance | 100,000 program/erase cycles - supports >10 years of daily firmware updates in deployed equipment |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Supply Voltage | 2.7–3.6 V - compatible with single-supply 3.3 V systems without level-shifting circuitry |
| Write Buffer Size | 16-word - reduces host-side overhead by batching writes before committing to flash array |
Pinout & Package
Package: 48-lead TSOP (Thin Small Outline Package), RoHS-compliant, lead-free, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| DQ0–DQ15 | Data I/O | x16 bidirectional data bus with internal latching; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; disables device and reduces current to 5 μA standby when high |
| OE# | Output Enable | Active-low output gate; controls data bus visibility without affecting internal state |
| WE# | Write Enable | Controls latching of address/data during command sequences; initiates internal program/erase on rising edge |
| WP# | Write Protect | Hardware lock for top boot block (B127–B134, 4 KWord each); grounded = protection enabled |
| RST# | Hardware Reset | Active-low signal forcing immediate return to Read mode; required after power-up initialization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF6401B-70-5I-TF | Same density and voltage range, but uniform 32 KWord block architecture (no 4 KWord boot sub-blocks); lacks Erase-Suspend | Suitable for simpler bootloaders without runtime update requirements; not recommended where suspend/resume is mandatory | Select only if design does not require Erase-Suspend or fine-grained boot block protection |
| MX29LV640ETTI-70G | 64 Mbit x16, 70 ns access, but requires 3.0–3.6 V supply (no 2.7 V support); no Write-Buffer Programming; different command set | Compatible for basic read/write in stable 3.3 V systems; incompatible with low-voltage brown-out recovery or high-speed buffered writes | Choose only when supply is strictly regulated at 3.3 V and firmware update speed is non-critical |
Compared with SST38VF6404BT-70-5I-TV, SST39VF6401B-70-5I-TF offers identical performance but reduced flexibility in protected boot regions, while MX29LV640ETTI-70G trades voltage tolerance and advanced programming features for broader distributor availability - making SST38VF6404BT-70-5I-TV optimal for designs needing guaranteed low-voltage operation, suspend-capable updates, and 4 KWord boot granularity.

FAQ
What is the operating temperature range for SST38VF6404BT-70-5I-TV?
The SST38VF6404BT-70-5I-TV is rated for industrial temperature operation from –40°C to +85°C, as indicated by the 'I' suffix in the part number. This range ensures reliable functionality in demanding environments such as factory-floor controllers and outdoor telecom equipment, where thermal cycling and ambient extremes are common. The device maintains specified 70 ns read access time and 100,000-cycle endurance across this full range.
Does SST38VF6404BT-70-5I-TV support hardware write protection for boot code?
Yes, SST38VF6404BT-70-5I-TV provides hardware boot block protection via the WP# pin, which - when grounded - locks the top 4 KWord boot blocks (B127–B134) against accidental program or erase operations. This complements software-based individual block protection and irreversible locking features, ensuring robust safeguarding of critical startup code in safety-certified systems.
How does the Write-Buffer Programming feature improve firmware update efficiency in SST38VF6404BT-70-5I-TV?
SST38VF6404BT-70-5I-TV's Write-Buffer Programming enables 16-word buffering with 1.75 μs per word effective programming time - reducing total write latency by over 80% compared to single-word writes. This accelerates field firmware patches and configuration updates, especially in resource-constrained microcontrollers lacking DMA support for flash writes.
Can SST38VF6404BT-70-5I-TV be used in systems requiring real-time firmware updates without service interruption?
Yes, SST38VF6404BT-70-5I-TV supports Erase-Suspend and Erase-Resume commands, allowing an active block-erase operation to be paused so that code or data can be read from or written to other unprotected blocks. This capability enables background firmware validation and incremental updates while maintaining uninterrupted real-time operation - essential for telecom base stations and medical devices.
What package type is used for SST38VF6404BT-70-5I-TV, and is it RoHS-compliant?
SST38VF6404BT-70-5I-TV is supplied in a 48-lead TSOP (Thin Small Outline Package) with standard x16 pinout, and all non-Pb (lead-free) variants are fully RoHS-compliant. The TSOP package supports automated SMT assembly and is pin-compatible with legacy parallel NOR flash sockets, simplifying migration from older generation devices.
