Overview of MT28F128J3RP-12 MET – IC FLASH 128MBIT PARALLEL 56TSOP
The MT28F128J3RP-12 MET is a 128 Mbit non-volatile FLASH memory device in a 56-pin TSOP package offering a parallel interface and industry-standard pinout. It provides x8/x16 memory organization with asynchronous page-mode reads and is specified for operation from 2.7 V to 3.6 V and ambient temperatures from -40 °C to +85 °C.
It is intended for system designs that require parallel FLASH storage for program code or data with features for block protection, suspend/resume operations, and vendor-identification support via Common Flash Interface (CFI).
Key Features
- Memory Capacity and Organization — 128 Mbit memory organized as 16M × 8 or 8M × 16, providing flexible bus-width options for parallel system interfaces.
- Flash Technology — Non-volatile FLASH memory with 128 KB erase blocks (one hundred twenty 128 KB blocks for the 128 Mb device).
- Access Performance — Asynchronous page-mode read timing quoted at 120 ns / 25 ns (128 Mb) for random and page-mode access respectively.
- Voltage Range — Single-supply operation and programming from 2.7 V to 3.6 V (VCC, VCCQ, and VPEN).
- Package — 56-pin TSOP (Type I) package; 56-TFSOP with 0.724" (18.40 mm) width.
- Interface and Compatibility — Parallel memory interface with industry-standard pinout and fully TTL-compatible inputs/outputs; supports Common Flash Interface (CFI) and Scalable Command Set.
- Write and Erase — Automatic write and erase algorithm with a 5.6 μs-per-byte effective programming time using the write buffer; block erase commands and suspend-to-read/program options.
- Data Protection and Security — 128-bit protection register, 64-bit unique device identifier, 64-bit user-programmable OTP cells, and flexible sector locking including erase/program lockout during power transition and VPEN = VSS enhanced protection.
- Reliability — Endurance specified at 100,000 erase cycles per block and support for program/erase suspend operations to minimize disruption to system reads or programming.
Typical Applications
- Embedded firmware storage — Parallel FLASH for storing system code and firmware images where non‑volatile program memory is required.
- System configuration and parameter storage — Use of OTP cells and unique device identifiers for device-specific configuration and asset tracking.
- Industrial and communications equipment — Non-volatile block storage with suspend/resume features to support in-system updates and read operations during program/erase cycles.
Unique Advantages
- Flexible bus-width support: x8 and x16 organization lets designs choose the data width that matches system requirements and simplifies board-level integration.
- Robust protection features: 128-bit protection register, sector locking and OTP options provide layered data protection and device identification.
- Suspend-to-read/program capability: Block erase and program suspend options allow read access during long program/erase operations, improving system responsiveness.
- CFI and standard command set: Common Flash Interface and Scalable Command Set enable predictable identification and command compatibility in system firmware.
- Extended temperature range: Specified operation from -40 °C to +85 °C supports a wide range of ambient environments.
