Product details
Overview
SST39VF1602-70-4C-B3KE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with 70 ns read access time, single 2.7–3.6V supply operation, and top 32 KWord hardware block protection. It features sector-erase (2 KWord), block-erase (32 KWord), and chip-erase capabilities, and is used in embedded firmware storage for industrial controllers and legacy communication modules requiring nonvolatile program memory with hardware write protection.
For engineers reviewing the SST39VF1602-70-4C-B3KE-T datasheet, SST39VF1602-70-4C-B3KE-T pinout, SST39VF1602-70-4C-B3KE-T application, or SST39VF1602-70-4C-B3KE-T equivalent, key selection considerations include its TSOP-48 package, JEDEC-standard x16 asynchronous interface, top-boot block protection scheme, and compatibility with standard flash command sets including CFI and Security ID.
Technical Context
The SST39VF1602-70-4C-B3KE-T implements SST's SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It supports JEDEC-standard command protocols-including six-byte sector/block/chip-erase sequences-and integrates hardware reset (RST#), write protect (WP#), and auto low-power mode (3 µA standby).
Its architecture includes latched address/data buses, toggle-bit (DQ6/DQ2) and data-polling (DQ7) status detection, and dual 128-bit Security ID space (factory + user). The device conforms to x16 flash pinouts and operates across industrial temperature range (–40°C to +85°C) with guaranteed 100,000 endurance cycles and >100-year data retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Bottom 32 KWord block protection instead of top; same density, speed, and package | Used where boot code resides at lowest address (000000H–007FFFH), not top | Select SST39VF1601C only if system requires bottom-boot architecture and new design flexibility |
| MX29LV160CTTI-70G | Same 16 Mbit x16, 70 ns, 2.7–3.6V; but uses different command set and lacks Security ID | Compatible in pinout and timing, but requires driver modification due to non-CFI command structure | Choose MX29LV160CTTI-70G only when CFI/Security ID features are unused and cost is primary constraint |
Compared with SST39VF1602-70-4C-B3KE-T, SST39VF1601C offers identical performance but reversed block protection orientation, while MX29LV160CTTI-70G provides pin-compatible timing but omits CFI and Security ID-requiring firmware adaptation for command handling and security functions.

FAQ
What does the "B3KE-T" suffix indicate in SST39VF1602-70-4C-B3KE-T?
The "B3KE-T" suffix denotes a 48-ball TFBGA package (B3), commercial temperature grade (C), lead-free and RoHS-compliant finish (E), and tape-and-reel packaging (T). This matches the device's physical form factor and compliance profile as specified in Microchip's DS25028A datasheet. SST39VF1602-70-4C-B3KE-T is not offered in TSOP; the "B3" explicitly identifies the TFBGA variant.
Is SST39VF1602-70-4C-B3KE-T pin-compatible with SST39VF1601 devices?
No - SST39VF1602-70-4C-B3KE-T and SST39VF1601 share identical pinouts and electrical interfaces, but differ in block protection mapping: SST39VF1602 protects the top 32 KWord (0F8000H–0FFFFFH), while SST39VF1601 protects the bottom 32 KWord (000000H–007FFFH). SST39VF1602-70-4C-B3KE-T must be used only where top-boot architecture is required.
Does SST39VF1602-70-4C-B3KE-T support Common Flash Interface (CFI)?
Yes - SST39VF1602-70-4C-B3KE-T fully supports JEDEC CFI via the standard three-byte entry sequence (5555H/AAH → 2AAAH/55H → 5555H/98H). CFI query returns geometry, timing, and command-set descriptors, enabling automatic driver initialization in BIOS and bootloader environments. SST39VF1602-70-4C-B3KE-T implements CFI Table 7–10 per DS25028A.
How is hardware write protection implemented on SST39VF1602-70-4C-B3KE-T?
SST39VF1602-70-4C-B3KE-T uses the WP# pin to enable top 32 KWord hardware block protection. When WP# is driven low, program and erase operations to addresses 0F8000H–0FFFFFH are inhibited. If left floating, WP# is internally pulled high, disabling protection. This mechanism is independent of software data protection and acts as a first-line defense against accidental firmware corruption. SST39VF1602-70-4C-B3KE-T does not support bottom-block protection.
What is the significance of "Not Recommended for New Designs" in the SST39VF1602-70-4C-B3KE-T datasheet?
Microchip marks SST39VF1602-70-4C-B3KE-T as "Not Recommended for New Designs" because it has been superseded by newer MPF+ variants like SST39VF1601C with enhanced reliability and extended lifecycle support. However, SST39VF1602-70-4C-B3KE-T remains fully qualified, in active production, and supported for existing designs - especially where top-boot protection and legacy CFI compatibility are mandatory. Aetrix Electronics guarantees supply continuity for SST39VF1602-70-4C-B3KE-T through planned obsolescence management.
