Product details
Overview
SST38VF6404-90-5I-B3KE from Microchip Technology is a 64 Mbit (4M × 16) CMOS Advanced Multi-Purpose Flash Plus memory IC, organized as 4,194,304 words × 16 bits, operating from 2.7–3.6 V, with 90 ns read access time and JEDEC-standard x16 pinout. It serves as nonvolatile program/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST38VF6404-90-5I-B3KE datasheet, SST38VF6404-90-5I-B3KE pinout, SST38VF6404-90-5I-B3KE application, or SST38VF6404-90-5I-B3KE equivalent, this device delivers fast page-read (25 ns), write-buffer programming (1.75 µs/word), 100,000-cycle endurance, hardware reset (RST#), and boot-block protection - critical for industrial control, networking boot code, and automotive ECUs.
Technical Context
The SST38VF6404-90-5I-B3KE implements SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command-set architecture supports JEDEC-standard x16 flash operations including Word-Program, Write-Buffer Programming (16-word buffer), Sector-Erase (4 KWord), Block-Erase (32 KWord), and Chip-Erase (40 ms typical).
It features dual status detection (DQ6 toggle bit, DQ7 data# polling), RY/BY# output for hardware busy signaling, WP#-controlled boot-block protection, and Erase-Suspend/Resume capability. The device supports Auto Low Power mode (3 µA standby) and latched address/data I/O compatible with standard microprocessor buses.

FAQ
What is the maximum operating temperature range for SST38VF6404-90-5I-B3KE?
The SST38VF6404-90-5I-B3KE is rated for industrial temperature operation from –40°C to +85°C, as confirmed by Microchip's DS20005015D datasheet Section 1.2. This makes SST38VF6404-90-5I-B3KE suitable for deployment in harsh environments such as factory floors, outdoor telecom cabinets, and under-hood automotive applications where thermal stability is critical.
Does SST38VF6404-90-5I-B3KE support hardware reset, and how is it implemented?
Yes, SST38VF6404-90-5I-B3KE includes an active-low hardware reset input (RST#) that forces the device into read mode and aborts any ongoing program or erase operation. As specified in Table 1 of DS20005015D, asserting RST# low for ≥100 ns returns SST38VF6404-90-5I-B3KE to known operational state - a key reliability feature for fail-safe embedded systems.
How does the Write-Buffer Programming feature improve firmware update speed in SST38VF6404-90-5I-B3KE?
SST38VF6404-90-5I-B3KE's 16-word Write-Buffer reduces average programming time from 7 µs/word (112 µs for 16 words) to 1.75 µs/word (28 µs total), achieving >4× speedup. This is enabled by loading data into the buffer first, then committing all 16 words to flash in one internal operation - a capability confirmed in DS20005015D Sections 9–10 for SST38VF6404-90-5I-B3KE.
Is SST38VF6404-90-5I-B3KE pin-compatible with SST38VF6401 or SST38VF6402?
Yes, SST38VF6404-90-5I-B3KE shares identical pinout, command set, and electrical specifications with SST38VF6401/6402/6403 per DS20005015D Section 1. All four variants use the same 48-ball TFBGA or 48-lead TSOP package and JEDEC x16 pin assignments - enabling drop-in replacement where boot-block location (top vs. bottom) aligns with system requirements.
What boot-block protection options are available on SST38VF6404-90-5I-B3KE?
SST38VF6404-90-5I-B3KE implements bottom-boot architecture: its 8 KWord boot block occupies sectors S1022–S1023 in Block B127. Protection is enforced via WP# pin (hardware lock), software individual block lock, and password protection - all documented in DS20005015D Tables 3 and 4 for SST38VF6404-90-5I-B3KE specifically.
