Product details
Overview
SST39VF1601C-70-4C-EKE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with JEDEC-standard x16 interface, 70 ns read access time, and bottom-boot block architecture. It operates from a single 2.7–3.6 V supply, supports hardware write protection via WP#, and delivers 100,000 program/erase cycles with >100 years data retention - ideal for embedded firmware storage in industrial controllers and legacy system BIOS.
For engineers reviewing the SST39VF1601C-70-4C-EKE-T datasheet, SST39VF1601C-70-4C-EKE-T pinout, SST39VF1601C-70-4C-EKE-T application, or SST39VF1601C-70-4C-EKE-T equivalent, key selection criteria include bottom-boot block address range (00000H–01FFFH), TSOP-48 package compatibility, RY/BY# status signaling, uniform 2 KWord sector erase, and SuperFlash® technology's fixed erase/program timing independent of cycle count.
Technical Context
This device implements SST's proprietary SuperFlash® technology with split-gate cell design and thick-oxide tunneling injector, enabling reliable single-voltage operation and eliminating need for external VPP generation. Its command-set architecture conforms to JEDEC standard x16 flash pinouts and supports Software Data Protection (SDP) with mandatory three-byte unlock sequences for programming and six-byte sequences for erasing.
The SST39VF1601C-70-4C-EKE-T features dedicated hardware block protection for the bottom 8 KWord boot sector (00000H–01FFFH), Auto Low Power mode reducing active read current to 3 µA after access, and dual status detection via DQ6 toggle bit and DQ7 data polling - all synchronized to WE#/CE# edge-triggered command latching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16), supporting 2 MB of firmware or configuration data |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in 5 MHz bus systems |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic rails without level shifting |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage |
| Erase Architecture | Uniform 2 KWord sectors + flexible blocks (31×32K, 1×16K, 2×4K, 1×8K) - enables granular update of boot code and application partitions |
| Write Protection | Hardware WP# pin protects bottom 8 KWord boot block (00000H–01FFFH) - prevents accidental overwrite of critical startup code |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, standard JEDEC x16 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 1M × 16 addressing (20-bit); AMS = A19 selects top/bottom boot block during erase |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during write; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; falling edge latches address during command sequences |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read operations |
| WE# | Write Enable | Active-low write control; rising edge initiates internal program/erase; latches data on first rise |
| WP# | Write Protect | Active-low hardware lock for bottom 8 KWord boot block (00000H–01FFFH) |
| RST# | Reset | Active-low hardware reset; forces return to read mode and aborts in-progress operations |
| RY/BY# | Ready/Busy# | Open-drain status output; low = active erase/program; requires 10–100 kΩ pull-up |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; powers internal charge pump for erase/program |
| VSS | Ground | Reference for all signals and internal circuitry |
| NC | No Connection | Unbonded pins (A16, A19 on TSOP); must be left floating or tied to VSS per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 18 ms sector/block erase and 7 µs word-program times - eliminates software de-rating across lifetime |
| Erase-Suspend/Resume | Allows reading from non-suspended sectors during erase - enables real-time status display or interrupt handling |
| Security ID Space | 128-bit factory-programmed SST ID + 128-word user-programmable space - supports device authentication and secure firmware binding |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts dynamic power in burst-read applications |
| JEDEC Compliance | Fully compatible with industry-standard x16 flash command sets and pinouts - simplifies migration from other vendors' parts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602C-70-4C-EKE-T | Top-boot block architecture (FE000H–FFFFFH) instead of bottom-boot; identical timing, voltage, and command set | Used where primary boot code resides in highest-address memory region, e.g., some x86 BIOS layouts | Select only if board design requires top-boot addressing; not pin-compatible due to differing protected block location |
| MX29LV160DTTI-70G | 16 Mbit x16 flash with 70 ns access, but uses different command sequences and lacks Erase-Suspend; no Security ID | Lower-cost alternative where suspend/resume and secure ID are not required | Requires firmware driver modification; verify RY/BY# timing and SDP compatibility before substitution |
Compared with SST39VF1602C-70-4C-EKE-T and MX29LV160DTTI-70G, the SST39VF1601C-70-4C-EKE-T uniquely combines bottom-boot protection, Erase-Suspend capability, and factory/user Security ID in a JEDEC-compliant TSOP-48 package - making it optimal for safety-critical firmware storage where boot integrity and field-upgrade flexibility are mandatory.

FAQ
What is the boot block configuration of the SST39VF1601C-70-4C-EKE-T?
The SST39VF1601C-70-4C-EKE-T implements bottom-boot block protection, covering the lowest 8 KWord address range (00000H–01FFFH). This is enforced by the WP# pin: when grounded, it prevents program and erase operations on that region. The protected block size and address are fixed per device variant and cannot be reconfigured in the SST39VF1601C-70-4C-EKE-T.
Does the SST39VF1601C-70-4C-EKE-T require an external VPP voltage for programming?
No, the SST39VF1601C-70-4C-EKE-T does not require external VPP. It uses internal charge pump circuitry powered solely by the 2.7–3.6 V VDD supply to generate necessary high voltages for erase and program operations - a core advantage of SST's SuperFlash® technology embedded in the SST39VF1601C-70-4C-EKE-T.
How is write operation completion detected on the SST39VF1601C-70-4C-EKE-T?
The SST39VF1601C-70-4C-EKE-T supports three concurrent methods: DQ6 toggle bit (alternating 1/0 during operation), DQ7 data polling (complement-to-data during program, 0 during erase), and RY/BY# open-drain status pin (low = busy). All are valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse in the command sequence.
Can the SST39VF1601C-70-4C-EKE-T be used in place of the SST39VF1602C-70-4C-EKE-T?
No - the SST39VF1601C-70-4C-EKE-T and SST39VF1602C-70-4C-EKE-T are not interchangeable. They differ in boot block location (bottom vs. top), protected address ranges (00000H–01FFFH vs. FE000H–FFFFFH), and device ID (234FH vs. 234EH). Substitution requires PCB-level verification of address decoding and firmware protection logic.
What is the purpose of the Security ID feature in the SST39VF1601C-70-4C-EKE-T?
The SST39VF1601C-70-4C-EKE-T includes a 136-word Security ID space: 128 bits factory-programmed by SST (read-only) and 128 words user-programmable. It enables hardware-bound device identification and secure firmware binding. Once locked via User Security ID Program Lock-Out command, the user segment becomes permanently immutable - a key trust anchor in the SST39VF1601C-70-4C-EKE-T.
