The compact TZ1201XBG graphics processor is based on a high-performance 32-bit ARM Cortex-M4F processor capable of operating at 96MHz (up to 120MHz with overdriving). Combining the ARM core with on-chip power management gives the TZ1201XBG a low power consumption of 70μA/MHz in active mode. With a 350mAh battery and an always-on display this enables around one month between charges in second watch applications - and two months for minute watches.

With 2.2MB of embedded high-speed SRAM, an advanced LCD controller and 2D graphics accelerators, the TZ1201XBG provides a powerful platform for alpha-blending, drawing, rotating, texturing and resizing images, and for on-the-fly color conversion. The fully-featured processor offers integrated support for either an HVGA (480x320) display at 30fps or a QVGA display (320x240) at up to 60fps.

The high-precision analogue front-end (AFE) combines a 24-bit delta-sigma ADC, 12-bit ADC, 12-bit DAC and an LED DAC thereby supporting direct sensing. These, in combination with software filtering, secure significant space and power savings.

120 free GPIOs and integrated USB, UART, SPI, and I2C interfaces support the use of external sensors and peripherals to monitor activity and movement, expanding the landscape of customer applications.

The integrated audio interfaces for voice command and voice trigger processing, and the 2D graphics accelerators, will allow Toshiba’s customers to deliver a higher level user experience.
