ST72651AR6 STMicroelectronics, ST72651AR6 Datasheet - Page 11

• Manufacturer Part Number: ST72651AR6
• Description: LOW-POWER, FULL-SPEED USB 8-BIT MCU WITH 32K FLASH, 5K RAM, FLASH CARD I/F, TIMER, PWM, ADC, I2C, SPI
• Manufacturer: STMicroelectronics

Specifications of ST72651AR6

• Dual Supply Management: analog voltage detector on the USB power line to enable smart power switching from USB power to battery (on E suffix devices).
• Programmable Internal Voltage Regulator For Memory Cards (2.8v To 3.5v) Supplying: Flash Card I/O lines (voltage shifting)
• 5 Usb Endpoints: 1 control endpoint
• Dtc (data Transfer Coprocessor): Universal Serial/Parallel communications interface, with software plug-ins for current and future protocol standards

Notes:
1. If the peripheral is present on the device (see Device Summary on page 1)
2. A weak pull-up can be enabled on PE5 input and open drain output by configuring the PEOR register
and depending on the PE5PU bit in the option byte.

Flash programming voltage. Must be held low in nor-
mal operating mode.
Bidirectional. This active low signal forces the initiali-
zation of the MCU. This event is the top priority non
maskable interrupt. This pin is switched low when the
Watchdog has triggered or V
to reset external peripherals.
