　　The Toshiba TMPM360F20FG is a Cortex-M3 based Microcontroller, 2048KB Flash ROM, 128KB SRAM, clock up to 64MHz, 4 channels Memory Controller, 2 channels DMA Controller 16 channels 16-bit Timer, 1 channel Real timer clock, 1 channel Watchdoc Timer, 12 channels UART, 5 channels I2C, 1 channel CEC, 1 channel Remote Control Signal Preprocessor, 97 Interrupts, 120 GPIO Pins, Standby mode, Clock generator (PLL), and On-Chip debugging (SWD, ETM).

　　The Cortex-M3 processor is a high performance 32-bit processor designed for the microcontroller market. It offers significant benefits to developers, including:

　　• outstanding processing performance combined with fast interrupt handling

　　• enhanced system debug with extensive breakpoint and trace capabilities

　　• efficient processor core, system and memories

　　• ultra-low power consumption with integrated sleep mode and an optional deep sleep Mode

　　• platform security robustness, with an optional integrated Memory Protection Unit (MPU).

　　The Cortex-M3 processor is built on a high-performance processor core, with a 3-stage pipeline Harvard architecture, making it ideal for demanding embedded applications. The processor delivers exceptional power efficiency through an efficient instruction set and extensively optimized design, providing high-end processing hardware including optional IEEE754-compliant single-precision floating-point computation, a range of single-cycle and SIMD multiplication and multiply-with-accumulate capabilities, saturating arithmetic and dedicated hardware division.

　　To facilitate the design of cost-sensitive devices, the Cortex-M3 processor implements tightly-coupled system components that reduce processor area while significantly improving interrupt handling and system debug capabilities. The Cortex-M3 processor implements a version of the Thumb® instruction set based on Thumb-2 technology, ensuring high code density and reduced program memory requirements. The Cortex-M3 instruction set provides the exceptional performance expected of a modern 32-bit architecture, with the high code density of 8-bit and 16-bit microcontrollers.

　　The Cortex-M3 processor closely integrates a configurable NVIC, to deliver industry-leading interrupt performance. The NVIC includes a Non-Maskable Interrupt (NMI) that can provide up to 256 interrupt priority levels. The tight integration of the processor core and NVIC provides fast execution of Interrupt Service Routines (ISRs), dramatically reducing the interrupt latency.

　　Cortex-M3处理器主要特性和优势:

　　• tight integration of system peripherals reduces area and development costs

　　• Thumb instruction set combines high code density with 32-bit performance

　　• code-patch ability for ROM system updates

　　• power control optimization of system components

　　• integrated sleep modes for low power consumption

　　• fast code execution permits slower processor clock or increases sleep mode time

　　• hardware division and fast digital-signal-processing orientated multiply accumulate

　　• deterministic, high-performance interrupt handling for time-critical applications

　　• optional MPU for safety-critical applications

　　• extensive implementation-defined debug and trace capabilities:

　　— Serial Wire Debug and Serial Wire Trace reduce the number of pins required for debugging, tracing, and code profiling.
