Product details
Overview
SST39SF010A-70-4C-WHE-T from Microchip Technology is a 1 Mbit (128K × 8) CMOS Multi-Purpose Flash memory IC with 70 ns read access time, single 4.5–5.5V supply operation, and uniform 4 KByte sector-erase architecture. It implements SuperFlash split-gate technology for high reliability and is used in embedded firmware storage, BIOS/UEFI code retention, and industrial controller configuration memory.
For engineers reviewing the SST39SF010A-70-4C-WHE-T datasheet, SST39SF010A-70-4C-WHE-T pinout, SST39SF010A-70-4C-WHE-T application, or SST39SF010A-70-4C-WHE-T equivalent, this page delivers verified technical context, JEDEC-compliant x8 interface timing, sector-level erase control, TTL I/O compatibility, and RoHS-compliant 32-lead TSOP packaging - all confirmed for the exact SST39SF010A-70-4C-WHE-T variant.
Technical Context
The SST39SF010A-70-4C-WHE-T uses SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 18 ms sector-erase and 14 µs byte-program times independent of endurance cycles. Its JEDEC-standard x8 pinout supports CE#/OE#/WE# control logic and latched address/data buses.
It operates across commercial temperature range (0°C to +70°C), requires no external VPP, generates internal high-voltage programming pulses, and provides dual end-of-write detection via Data# Polling (DQ7) and Toggle Bit (DQ6) - both valid after the fourth WE# or CE# pulse during byte-program operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128K × 8), directly maps to 128 KB of nonvolatile program/data storage |
| Read Access Time | 70 ns - determines maximum sustained read throughput in legacy 8-bit bus systems |
| Supply Voltage | 4.5–5.5V - compatible with standard 5V TTL logic rails without level-shifting |
| Endurance | 100,000 program/erase cycles - supports frequent field firmware updates over product lifetime |
| Data Retention | Greater than 100 years - ensures long-term integrity of boot code and calibration data |
| Active Current | 10 mA typical at 14 MHz - enables low-power operation in battery-backed or energy-constrained systems |
| Standby Current | 30 µA typical - minimizes quiescent power draw during system sleep modes |
Pinout & Package
Package: 32-lead TSOP (8 mm × 14 mm), RoHS-compliant, surface-mountable with standard JEDEC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K × 8 memory space; A16 is most significant bit for SST39SF010A |
| DQ0–DQ7 | Data Input/Output | 8-bit bidirectional data bus; tri-stated when CE# or OE# is high; latched internally during write |
| CE# | Chip Enable | Active-low chip select; device enters standby mode (30 µA) when high |
| OE# | Output Enable | Active-low output gate; controls data bus visibility without affecting internal state |
| WE# | Write Enable | Active-low write strobe; initiates byte-program or sector-erase upon rising edge sequence |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160CBTI-70G | 16 Mbit (2M × 8), 3.0V core, 70 ns access, different command set and sector map | Requires voltage translation for 5V systems; larger density may increase cost and PCB footprint | Select only if migrating to 3.3V design and requiring higher capacity |
| EN29LV010 | 1 Mbit (128K × 8), 3.0V core, 70 ns access, similar JEDEC x8 pinout but distinct unlock sequence | Not 5V-tolerant; requires level-shifting in legacy 5V bus environments | Use only in new 3.3V designs where Microchip SST39SF010A-70-4C-WHE-T's 5V native operation is unnecessary |
Compared with MX29LV160CBTI-70G and EN29LV010, the SST39SF010A-70-4C-WHE-T uniquely delivers native 5V operation, fixed-program timing, and proven 100,000-cycle endurance in industrial temperature range - making it the optimal choice for maintaining legacy 5V embedded systems without redesign.

FAQ
What is the exact memory organization of the SST39SF010A-70-4C-WHE-T?
The SST39SF010A-70-4C-WHE-T is organized as 128K × 8, delivering 1 Mbit (131,072 bytes) of nonvolatile storage. Its 17 address lines (A0–A16) fully decode the address space, and it uses uniform 4 KByte sectors for erase operations - a structure confirmed in the official Microchip DS20005022C datasheet for the SST39SF010A-70-4C-WHE-T.
Does the SST39SF010A-70-4C-WHE-T require an external VPP voltage for programming?
No, the SST39SF010A-70-4C-WHE-T does not require external VPP. It integrates an internal charge pump that generates the high voltage needed for erase and program operations from the single 4.5–5.5V VDD supply - a key feature of SST's SuperFlash architecture confirmed for the SST39SF010A-70-4C-WHE-T in its datasheet.
What is the guaranteed operating temperature range for the SST39SF010A-70-4C-WHE-T?
According to the official Microchip datasheet DS20005022C, the SST39SF010A-70-4C-WHE-T is rated for commercial temperature operation from 0°C to +70°C. The "4C" in the part number explicitly denotes this commercial grade, and the device is not qualified for industrial (–40°C to +85°C) or extended ranges.
How does the SST39SF010A-70-4C-WHE-T indicate completion of a byte-program operation?
The SST39SF010A-70-4C-WHE-T supports two hardware-confirmed methods: Data# Polling (monitoring DQ7 for true data return) and Toggle Bit (observing toggling on DQ6 until it stabilizes). Both are valid after the rising edge of the fourth WE# or CE# pulse - a behavior explicitly defined for the SST39SF010A-70-4C-WHE-T in Table 4 and Figure 8 of its datasheet.
Is the SST39SF010A-70-4C-WHE-T pin-compatible with other devices in the SST39SFxxxA family?
Yes - the SST39SF010A-70-4C-WHE-T shares identical pinout, command set, and electrical interface with SST39SF020A and SST39SF040 in the same 32-lead TSOP package. However, address depth differs: SST39SF010A uses A0–A16 (17 bits), while SST39SF020A adds A17 and SST39SF040 adds A18 - confirmed in Figures 2–4 and Table 1 of the SST39SF010A-70-4C-WHE-T datasheet.
