Product details
Overview
SST38VF6404BT-70-5I-CD 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 from 2.7–3.6 V, delivers 70 ns read access time and 25 ns page read access, supports 100,000 erase/program cycles, and features hardware boot block protection via WP# pin.
For engineers reviewing the SST38VF6404BT-70-5I-CD datasheet, SST38VF6404BT-70-5I-CD pinout, SST38VF6404BT-70-5I-CD application, or SST38VF6404BT-70-5I-CD equivalent, key selection considerations include its 48-lead TSOP package, uniform 32 KWord block architecture with top-boot configuration, 16-word write buffer, and JEDEC-compliant x16 interface for microcontroller-based firmware storage and field-upgradable systems.
Technical Context
This device implements SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It uses standard JEDEC x16 command sets and CFI compliance for interoperability with legacy flash controllers.
Its dual-mode operation includes standard Word-Program (7 μs typical) and accelerated Write-Buffer Programming (1.75 μs/word typical), with status detection via DQ7 Data# Polling, DQ6 Toggle Bit, and RY/BY# output. Block-Erase (18 ms) and Chip-Erase (40 ms) are supported, along with Erase-Suspend/-Resume for concurrent read/program during erase.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF6401B-70-5I-B3QE | 48-ball TFBGA package; identical 4M×16 organization, 70 ns access, and SuperFlash architecture | Surface-mount footprint optimized for space-constrained PCBs; no through-hole compatibility | Select when board area is constrained and BGA assembly capability exists |
| MX29LV640ETTI-70G | 64 Mbit x16, 70 ns access, but uses conventional floating-gate technology-erase/program times increase with cycle count | Lacks Erase-Suspend and Auto Low Power modes; lower endurance (100K vs. same, but degrades) | Choose only if legacy design reuse requires pin-compatible replacement without feature validation |
Compared with SST38VF6404BT-70-5I-CD, the SST39VF6401B-70-5I-B3QE offers identical functionality in a smaller TFBGA package, while the MX29LV640ETTI-70G provides basic x16 flash compatibility but lacks SuperFlash's fixed timing, suspend capability, and ultra-low power modes-making it unsuitable for field-upgrade-critical or energy-sensitive designs.

FAQ
What is the memory organization and density of the SST38VF6404BT-70-5I-CD?
The SST38VF6404BT-70-5I-CD is organized as 4M × 16, delivering 64 Mbit (8 MByte) of nonvolatile flash memory. This configuration supports 16-bit parallel data transfers and addresses up to 4,194,304 words using A0–A21. Its density and x16 interface make it ideal for microcontroller-based systems requiring compact, high-bandwidth firmware storage-exactly matching the specification sheet DS20005002D for the SST38VF6404B variant.
Does the SST38VF6404BT-70-5I-CD support hardware write protection, and how is it implemented?
Yes, the SST38VF6404BT-70-5I-CD implements hardware write protection via the WP# (Write Protect) pin. When WP# is grounded, it permanently protects the top boot block (B127–B134, 4 KWord each) from erase and program operations. This protection is independent of software commands and remains active even during power cycling-ensuring bootloader integrity in safety-critical applications like automotive ECUs and medical devices where accidental corruption must be physically prevented.
What package type and pin count does the SST38VF6404BT-70-5I-CD use?
The SST38VF6404BT-70-5I-CD uses a 48-lead TSOP (Thin Small Outline Package) with standard JEDEC x16 pinout. It is not offered in TFBGA for this specific speed grade and temperature rating. The "T" in the part number denotes TSOP packaging, and the "5I" suffix confirms industrial temperature range (–40°C to +85°C). Pin assignments match Figures 2-1 and Table 2-1 in DS20005002D, including dedicated VSS pins and NC (No Connect) at position A16 in TSOP.
How does the SST38VF6404BT-70-5I-CD handle status reporting during program or erase operations?
The SST38VF6404BT-70-5I-CD provides three concurrent status reporting methods: DQ7 Data# Polling, DQ6 Toggle Bit, and the RY/BY# output pin. During internal operations, DQ7 toggles between complemented data and valid data; DQ6 alternates between 0 and 1 until completion; and RY/BY# goes low to signal active programming or erasing. These mechanisms allow flexible polling or interrupt-driven firmware control-enabling efficient use of CPU resources during long-duration flash operations in the SST38VF6404BT-70-5I-CD.
Is the SST38VF6404BT-70-5I-CD RoHS compliant and lead-free?
Yes, the SST38VF6404BT-70-5I-CD is fully RoHS compliant and lead-free. As stated in the official Microchip datasheet DS20005002D-page 1, "All non-Pb (lead-free) devices are RoHS compliant." The "-5I" suffix confirms industrial temperature grade and RoHS-compliant packaging. No exemptions or alternate material sets apply-the device meets Directive 2011/65/EU requirements without deviation, making it suitable for global electronics manufacturing and export.
