6 / 19 page System description STA2064 6/19 Doc ID 16057 Rev 1 2.3.6 Real-time clock (RTC) The RTC provides a one second resolution clock. This keeps time when the system is inactive and can be used to wake the system up when a programmed ‘alarm’ time is reached. It has a clock trimming feature to compensate the drift of the 32.768 kHz crystal. 2.3.7 Real-time timer (RTT) The RTT has the possibility of being clocked off. This reduces the always_on domain consumption during Deep Sleep. By default the RTT has its clock enabled. 2.3.8 Always_ON supply The “Always_ON” domain retains its two separate supplies, one for the core logic (VDDON) and one for the IOs (VIOON). The VDDON supply is equal to VDD during normal operation but, with the goal of reaching the lowest consumption possible, can also be configured as low as 1.0 ±10%V when the device is in deep-sleep. 2.3.9 Enhanced function timer (EFT) STA2064 features 4 16-bit EFTs. Each of the four EFT timers has a 16-bit free-running counter with 7-bit prescaler, up to two input capture/output compare functions, a pulse counter function, and a PWM channel with selectable frequency. 2.3.10 Watchdog timer (WDT) This OS resource is used to trigger a system reset in the event of software failure. 2.4 Memory interfaces 2.4.1 SD/MMC STA2064 features two SD/SDIO/MMC interfaces up to 52 MHz / one up to 8-bit data, the other up to 4-bit data. The main clock available to the peripherals is: ● PLL2CLK/13 (when PLL2CLK is 624 MHz and SRC_MMC52 = 0, 48 MHz will be generated) ● PLL2CLK/12 (when PLL2CLK is 624 MHz and SRC_MMC = 1, 52 MHz will be generated) ● PLL2CLK/9 (when PLL2CLK is 432 MHz, 48 MHz will be generated) The peripheral is compliant to the following standards: ● MMC 4.4 ● SD 2.0/Part 1 - Physical Layer ● SD 2.0/Part E1 - SDIO Specification |
