Product details
Overview
SST39VF1601-70-4C-B3KE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with 70 ns read access time, single 2.7–3.6 V supply operation, and bottom 32 KWord hardware block protection. It supports sector-erase (2 KWord), block-erase (32 KWord), chip-erase, and erase-suspend/resume functions, and is used in embedded firmware storage for industrial controllers and legacy communication modules requiring nonvolatile code retention.
For engineers reviewing the SST39VF1601-70-4C-B3KE datasheet, SST39VF1601-70-4C-B3KE pinout, SST39VF1601-70-4C-B3KE application, or SST39VF1601-70-4C-B3KE equivalent, key selection considerations include JEDEC-standard x16 asynchronous interface compatibility, TSOP-48 package footprint, 100,000-cycle endurance, 100-year data retention, and hardware write-protection via WP# for boot-block integrity.
Technical Context
The SST39VF1601-70-4C-B3KE implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command-set architecture conforms to JEDEC standard flash pinouts and supports software data protection (SDP) with three-byte unlock sequences for program and six-byte sequences for erase operations.
It features dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for end-of-write verification, Auto Low Power mode reducing active read current from 9 mA to 3 µA after valid access, and CFI Query support for runtime device characterization. The RST# pin provides hardware reset to Read mode with guaranteed recovery timing.

FAQ
What is the memory organization and density of the SST39VF1601-70-4C-B3KE?
The SST39VF1601-70-4C-B3KE is organized as 1M × 16, providing 16 Mbit (2 MB) of nonvolatile storage. This x16 parallel interface supports direct connection to 16-bit microcontrollers and DSPs without data multiplexing. Its density and addressing scheme (A0–A18) are fully defined in the SST39VF1601-70-4C-B3KE datasheet Table 9, confirming 512 uniform 4 KB sectors and 32 uniform 64 KB blocks.
Does the SST39VF1601-70-4C-B3KE support hardware write protection, and how is it configured?
Yes, the SST39VF1601-70-4C-B3KE implements bottom 32 KWord hardware block protection via the WP# pin. When WP# is driven low, program and erase operations are disabled for addresses 000000H–007FFFH-the boot block region. This protection is active regardless of software commands and remains effective during power transitions, making it essential for safeguarding bootloader code in the SST39VF1601-70-4C-B3KE.
What are the supported erase methods for the SST39VF1601-70-4C-B3KE, and what are their typical durations?
The SST39VF1601-70-4C-B3KE supports sector-erase (2 KWord), block-erase (32 KWord), and chip-erase. Typical durations are 18 ms for sector/block-erase and 40 ms for chip-erase, all internally timed and independent of cycle count due to SuperFlash technology. These values are measured under standard conditions (VDD = 3.0 V, TA = 25°C) and confirmed in the SST39VF1601-70-4C-B3KE datasheet Section 1.
How does the SST39VF1601-70-4C-B3KE indicate completion of a program or erase operation?
The SST39VF1601-70-4C-B3KE provides two hardware-supported status detection methods: Data# Polling on DQ7 (complement-to-data during operation, true data upon completion) and Toggle Bit on DQ6 (toggles between 0/1 during operation, stops toggling when complete). Both are valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse, as specified in the SST39VF1601-70-4C-B3KE timing diagrams.
Is the SST39VF1601-70-4C-B3KE still recommended for new designs, and what is the suggested alternative?
No, the SST39VF1601-70-4C-B3KE is marked "Not Recommended for New Designs" per Microchip DS25028A (08/11). The officially recommended replacement is SST39VF1601C-70-4C-B3KE, which maintains pin, package, and functional compatibility while offering enhanced ESD performance and updated manufacturing process control for sustained availability.
