Product details
Overview
SST39SF010A-70-4I-WHE-T from Microchip Technology is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with JEDEC-standard x8 parallel interface, 70 ns read access time, single 4.5–5.5V supply operation, and uniform 4 KByte sector-erase architecture. It is used for firmware storage and configuration code in industrial control panels requiring field-upgradable nonvolatile memory.
For engineers reviewing the SST39SF010A-70-4I-WHE-T datasheet, SST39SF010A-70-4I-WHE-T pinout, SST39SF010A-70-4I-WHE-T application, or SST39SF010A-70-4I-WHE-T equivalent, this page delivers verified package mapping (32-lead TSOP), JEDEC-compliant command set, SuperFlash reliability metrics (100,000 program/erase cycles, >100 years data retention), and hardware/software data protection implementation details.
Technical Context
The SST39SF010A-70-4I-WHE-T implements SST's proprietary SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program timing independent of cycle count-unlike conventional flash where timing degrades over endurance life. Its 128K × 8 organization uses A0–A16 address lines (AMS = A16), with CE#, OE#, and WE# controlling device selection, output gating, and write initiation respectively.
It supports three primary operations via JEDEC-standard command sequences: Byte-Program (20 µs typical), Sector-Erase (18 ms typical, 4 KByte uniform sectors), and Chip-Erase (70 ms typical). End-of-write detection is implemented via Data# Polling (DQ7) and Toggle Bit (DQ6), both valid after the fourth WE#/CE# pulse during programming and sixth pulse during erase.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT29LV010A-12JC | 1 Mbit, 120 ns access, 3.0–3.6V supply only - requires level-shifting for 5V systems | Designed for low-voltage embedded systems; not suitable for legacy 5V bus interfaces | Select only if system operates at 3.3V and timing budget allows 120 ns latency |
| MX29LV160CBTI-70G | 16 Mbit density, 70 ns access, 2.7–3.6V supply - incompatible voltage domain and pinout | Targeted at modern 3.3V microcontrollers with larger firmware footprints | Not a functional substitute; requires PCB redesign and firmware adaptation |
Compared with AT29LV010A-12JC and MX29LV160CBTI-70G, the SST39SF010A-70-4I-WHE-T uniquely supports 5V-only operation with JEDEC-compliant pinout and command set, making it the only viable drop-in replacement for legacy 5V parallel flash designs requiring 70 ns timing and industrial temperature range.

FAQ
What is the maximum operating temperature range for the SST39SF010A-70-4I-WHE-T?
The SST39SF010A-70-4I-WHE-T is rated for industrial temperature operation from -40°C to +85°C, as confirmed in Table 5 of the official Microchip datasheet DS20005022C. This specification applies to all electrical characteristics including 70 ns read access time, 100,000-cycle endurance, and software command execution. The "I" suffix in the part number explicitly denotes industrial temperature grade, distinguishing it from commercial-grade variants.
Does the SST39SF010A-70-4I-WHE-T require an external VPP voltage for programming?
No, the SST39SF010A-70-4I-WHE-T does not require an external VPP voltage. As stated in the Features section of the datasheet, it includes internal VPP generation powered solely by the 4.5–5.5V VDD supply. All program and erase operations-including Byte-Program (20 µs), Sector-Erase (18 ms), and Chip-Erase (70 ms)-are performed using only the main VDD rail, eliminating the need for dedicated high-voltage programming circuitry in the host system design.
How many address lines does the SST39SF010A-70-4I-WHE-T use, and what is the significance of AMS?
The SST39SF010A-70-4I-WHE-T uses 17 address lines (A0–A16), where AMS (Address Most Significant) = A16. This is explicitly defined in Table 1 and Figures 2–4 of the datasheet. The 17-bit address bus supports the full 128K × 8 organization (131,072 bytes), enabling direct linear addressing without banking. AMS = A16 is critical for correct sector-address decoding during Sector-Erase commands, as only A0–A12 are used to select the 4 KByte sector.
Is the SST39SF010A-70-4I-WHE-T pin-compatible with other devices in the SST39SFxxxA family?
Yes, the SST39SF010A-70-4I-WHE-T shares identical pinout and command set with SST39SF020A and SST39SF040 in the same 32-lead TSOP package, as confirmed in Figures 3 and Table 1 of the datasheet. All three devices conform to JEDEC standard x8 flash pinouts. However, address line usage differs: SST39SF020A uses A17 as AMS, and SST39SF040 uses A18 as AMS-meaning external address decoding logic must accommodate the expanded range for higher-density variants.
What data protection mechanisms are implemented in the SST39SF010A-70-4I-WHE-T?
The SST39SF010A-70-4I-WHE-T implements dual-layer data protection: hardware-level noise/glitch rejection (<5 ns pulse immunity), VDD power-up/down detection (write inhibited below 2.5V), and Write Inhibit Mode (forced by OE# low, CE# high, or WE# high); plus software-level JEDEC-compliant command sequences requiring 3-byte loads for programming and 6-byte loads for erasing-both permanently enabled at shipment per Table 4 and Product Identification section.
