Product details
Overview
TE28F128P30T85A from Intel is a 128-Mbit (8M × 16) parallel NOR flash memory with 3.0 V single-supply operation, 85 ns access time, and x16 data bus width. It supports CFI-compliant command sets, sector-erase architecture, and operates across industrial temperature range (–40°C to +85°C), used in boot code storage for network routers and industrial controllers.
For engineers reviewing the TE28F128P30T85A datasheet, TE28F128P30T85A pinout, TE28F128P30T85A application, or TE28F128P30T85A equivalent, key selection criteria include erase granularity, write cycle endurance, VCC tolerance, JEDEC-standard packaging, and compatibility with legacy parallel-addressed microcontroller boot interfaces.
Technical Context
This device implements a standard parallel asynchronous interface with address latching via ALE and data/control separation using CE#, OE#, and WE# control signals. It uses a 48-pin TSOP package with 27 address lines (A0–A26) supporting full 8M-word addressing and 16-bit bidirectional data I/O (DQ0–DQ15).
The memory array is organized into 128 uniform sectors of 64 Kbytes each, enabling flexible firmware update strategies. Command execution follows Intel's proprietary command set (e.g., 0x60 + 0xD0 for chip erase), and status polling via DQ7/DQ6 supports embedded erase/write completion detection without requiring external wait-state logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Type | Parallel NOR Flash - enables direct XIP (execute-in-place) boot code execution without RAM loading |
| Capacity | 128 Mbit (8M × 16) - supports up to 8 million 16-bit instructions or configuration tables |
| Access Time | 85 ns - meets timing budget for 12 MHz microcontroller bus interfaces with no wait states |
| Supply Voltage | 3.0 V ± 0.3 V - compatible with 3.3 V LDO-regulated systems; no separate VPP required |
| Endurance | 100,000 program/erase cycles per sector - sufficient for field firmware updates over 10+ years |
| Data Retention | 20 years at 85°C - validated for industrial deployment in uncooled enclosures |
| Operating Temp | –40°C to +85°C - qualified for extended-temperature industrial control and telecom infrastructure |
Pinout & Package
TE28F128P30T85A is housed in a 48-pin Thin Small Outline Package (TSOP Type I, 12 × 20 mm, 0.5 mm pitch), compliant with JEDEC MO-142AA. Pin functions are electrically and mechanically defined for socketed or soldered PCB mounting in legacy parallel-memory designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A26 | Address Inputs | 27-bit address bus supporting full 8M-word linear addressing; A0 selects LSB of 16-bit word |
| DQ0–DQ15 | Data I/O | Bidirectional 16-bit data bus; high-impedance during read hold or standby to prevent bus contention |
| CE# | Chip Enable | Active-low enable controlling device selection; must be asserted before OE# or WE# for valid access |
| OE# | Output Enable | Active-low read strobe; gates output drivers but does not affect internal state or timing |
| WE# | Write Enable | Active-low write strobe; initiates command latching or data programming on rising edge |
| RY/BY# | Ready/Busy Output | Open-drain status indicator: low = operation in progress; high = ready for next command |
Key Features
| Feature | Design Value |
|---|---|
| CFI Compliant Interface | Enables automatic software detection of geometry, timing, and command set via standardized query mode |
| Sector-Erase Architecture | 128 uniform 64-KB sectors allow selective firmware patching without full chip erase |
| Embedded Algorithms | On-chip erase and program algorithms eliminate need for external timing or sequence control logic |
| Status Register Polling | DQ7 (Data# Polling) and DQ6 (Toggle Bit) provide real-time operation status without interrupt dependency |
| VCC Power-Down Mode | Reduces standby current to 1 µA, enabling low-power retention in battery-backed systems |
Applications
| Network Router Boot Storage | Industrial PLC Firmware |
|---|---|
Use Scenario: Storing boot loader and initial firmware image in carrier-grade edge routers requiring cold-start reliability. IC Role / Device Role / Timing Role: Primary nonvolatile boot memory mapped directly to CPU address space; executes XIP during power-on reset sequence. Use Value: 85 ns access time ensures boot completion within 200 ms; sector erase enables field-upgradable bootloader patches. | Use Scenario: Holding control logic firmware and configuration parameters in programmable logic controllers deployed in factory automation. IC Role / Device Role / Timing Role: Nonvolatile program storage with deterministic read latency for cyclic scan execution timing. Use Value: 20-year data retention at 85°C guarantees firmware integrity in unventilated control cabinets. |
| Telecom Base Station BIOS | Military Vehicle Control Module |
Use Scenario: Hosting BIOS and FPGA configuration bitstreams in 4G/LTE base station remote radio units exposed to wide thermal cycling. IC Role / Device Role / Timing Role: Dual-role memory: boot ROM and static configuration store accessed during initialization and runtime reconfiguration. Use Value: CFI compliance allows unified driver support across multiple Intel flash generations in multi-vendor hardware platforms. | Use Scenario: Securing mission-critical startup routines and calibration data in armored vehicle electronic control units operating under shock/vibration. IC Role / Device Role / Timing Role: Radiation-tolerant (non-SEL) parallel flash providing fail-safe boot path independent of volatile memory subsystems. Use Value: 100,000-cycle endurance supports in-field software reflash during depot-level maintenance without replacement. |
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 |
|---|---|---|---|
| S29GL128P11TFI010 | 128 Mbit, 110 ns access, 3.0 V, 64-pin TSOP - slower timing, larger package | Requires PCB redesign due to pin count and layout footprint mismatch | Use only if board revision accommodates 64-pin footprint and timing margin permits 110 ns |
| MX29GL128FHT2I-90G | 128 Mbit, 90 ns access, 3.0 V, 48-pin TSOP - 5 ns slower, different command set | Non-CFI interface requires custom driver adaptation; no automatic geometry detection | Select when cost sensitivity outweighs software portability and CFI toolchain benefits |
Compared with S29GL128P11TFI010 and MX29GL128FHT2I-90G, TE28F128P30T85A offers optimal balance of speed, pin compatibility, and software interoperability for legacy parallel-boot designs where CFI-based auto-configuration and 85 ns timing are design requirements.

FAQ
Is TE28F128P30T85A compatible with 3.3 V I/O interfaces?
No. TE28F128P30T85A is a 3.0 V core and I/O device with absolute maximum VIO rating of 3.6 V. Interfacing directly to 3.3 V logic without level translation risks parametric violation during voltage transients and is not supported per Intel's DC characteristics table.
Does this device support byte-write operations?
No. TE28F128P30T85A only supports 16-bit word programming. The device lacks internal byte-write logic or address masking; attempts to write individual bytes result in undefined behavior or data corruption.
Can TE28F128P30T85A be used in new designs given Intel's exit from flash business?
Yes. TE28F128P30T85A remains actively supported through authorized distribution channels with documented lifetime buy programs, controlled change notifications, and guaranteed last-time-buy windows aligned to industrial product lifecycles.
What is the minimum VCC required for valid command execution?
The minimum functional VCC is 2.7 V per Intel's datasheet Absolute Maximum Ratings and DC Characteristics. Below 2.7 V, command recognition, erase verification, and data retention are not guaranteed; system-level brown-out detection must enforce this threshold.
