TMPM365 Microcontroller from Toshiba Simplifies USB Designs

The TMPM365 integrates the ARM Cortex-M3 core, a USB device controller, a 12-channel analogue-to-digital converter, on-chip program and data memory, timers and configurable serial connectivity options into a BGA package measuring just 9mm x 9mm. Maximum processor speed is 48MHz and an integrated clock generator supports clock gearing of 1/1, 1/2, 1/4 and 1/8. Use of the low-power ARM core and high-efficiency NANOFLASH™ memory - as well as the availability of IDLE and STOP standby modes - all contribute to low power consumption in target application.



Compliant with USB 2.0, the single-channel USB device controller offers full-speed 12Mbps operation and supports eight endpoints. The 12-bit ADC offers high-speed 1µs conversion and can start up from an internal 16-bit timer or external trigger input. On-board memory comprises 256Kbytes of NANOFLASH ROM, 24Kbytes of SRAM and Boot ROM. A 2-channel DMA controller supports on-chip and external memory and peripheral I/O.



The TMPM365 incorporates a single-channel watchdog timer and a 10-channel 16-bit timer. Connectivity options include a general-purpose serial interface that can be configured for UART or synchronous mode operation and a 2-channel serial bus interface selectable between I2C and synchronous mode.



Toshiba’s new microcontroller has an input voltage range of 2.7V to 3.6V when operating with the on-chip regulator or 3.0V to 3.45V when powered via USB. Rated operating temperature is -40°C to 85°C.
