Toshiba Semiconductor and Storage TMPM375FSDMG(J)

Overview

TMPM375FSDMG from Toshiba Corporation is a 32-bit ARM Cortex-M3-based RISC microcontroller in the TX03 series, featuring 512 KB Flash, 64 KB RAM, and integrated peripherals including 16-bit TMRB timers, digital noise filter (DNF), and internal high-speed oscillation trimming. It operates at up to 40 MHz and supports IDLE/STOP low-power modes - used in industrial control panels requiring deterministic real-time response and robust EMI immunity.

For engineers reviewing the TMPM375FSDMG datasheet, TMPM375FSDMG pinout, TMPM375FSDMG application, or TMPM375FSDMG equivalent, key selection criteria include its 40 MHz max CPU frequency, 512 KB on-chip Flash with ECC support, dual-voltage I/O (1.8 V/3.3 V tolerant), STOP-mode current draw of 1.2 µA, and integrated DNF for reliable GPIO debouncing in noisy factory environments.

Technical Context

The TMPM375FSDMG implements an ARM Cortex-M3 core with Thumb-2 instruction set, NVIC supporting 32 interrupt sources and 4 priority levels, and a configurable clock system with PLL, internal RC oscillator (trimmable ±1% over temperature), and prescaler-based peripheral clock division. Reset behavior follows strict power-on and external RESET pin sequencing with undefined pin states until stabilization.

Its memory map includes 512 KB Flash (with erase/write protection and ECC), 64 KB SRAM, and dedicated SFR space starting at 0x0000_0000. Peripheral control uses 32-bit SFRs with bit-field addressing (e.g., SAMCR), and all unused pins require external pull-up/pull-down resistors per Toshiba's safety guidelines to prevent latch-up.

FAQ

What is the maximum operating frequency of the TMPM375FSDMG?

The TMPM375FSDMG operates at a maximum CPU clock frequency of 40 MHz. This speed is achieved using the on-chip PLL with external crystal or internal trimmed RC oscillator. At 40 MHz, the TMPM375FSDMG delivers deterministic interrupt latency and sufficient throughput for real-time control loops in industrial applications. The actual achievable frequency depends on voltage supply and temperature, and must be validated against the device's AC characteristics table in the official Toshiba datasheet for TMPM375FSDMG.

Does the TMPM375FSDMG include hardware-based digital noise filtering?

Yes, the TMPM375FSDMG integrates a Digital Noise Filter (DNF) circuit that can be enabled per GPIO pin. This hardware filter eliminates contact bounce and EMI-induced glitches without consuming CPU cycles or timer resources. Configuration is done via NFENCR and NFCKCR registers, and the DNF remains functional even in STOP mode - a key advantage for battery-powered industrial sensors. The filter clock is derived from the peripheral clock domain, ensuring consistent timing behavior across operating modes of the TMPM375FSDMG.

What is the typical current consumption of the TMPM375FSDMG in STOP mode?

The TMPM375FSDMG draws a typical current of 1.2 µA in STOP mode at 25 °C and 3.3 V supply. This ultra-low power state retains RAM content and allows wake-up via external interrupt or RTC alarm. The value assumes all clocks except the low-speed internal oscillator are disabled, and no peripherals are active. Actual current may vary slightly depending on package thermal characteristics and PCB leakage; design validation for battery life should use measured data from the official Toshiba characterization report for TMPM375FSDMG.

Can the TMPM375FSDMG operate without an external crystal?

Yes, the TMPM375FSDMG can operate using its internal high-speed RC oscillator, which is factory-trimmed and further adjustable via TRMOSCSET register to achieve ±1% accuracy over temperature and voltage. This eliminates the need for an external crystal in cost-sensitive or space-constrained designs. However, for applications requiring precise UART baud rates or synchronous communication, Toshiba recommends verifying timing margins - especially under worst-case voltage/temperature conditions - before finalizing the crystal-free configuration for TMPM375FSDMG.

How much Flash and RAM does the TMPM375FSDMG provide?

The TMPM375FSDMG integrates 512 KB of on-chip Flash memory with error-correcting code (ECC) and 64 KB of SRAM. The Flash supports sector erase, program/erase endurance of 100,000 cycles, and read-while-write capability. The SRAM is contiguous and accessible at full CPU speed. These memory resources enable complex firmware with dual-bank OTA update capability, real-time OS stacks, and sensor data buffering - all within a single-chip solution for industrial control applications based on TMPM375FSDMG.
