• Manufacturer Part Number: ST72321AR6-Auto
• Description: 8-bit MCU for automotive with 32 Kbyte Flash, 10-bit ADC, timers, SPI, SCI and I2C interfaces
• Manufacturer: STMicroelectronics

Specifications of ST72321AR6-Auto

• Hdflash Endurance: 100 cycles, data retention 20 years
• Clock Sources: crystal/ceramic resonator oscillators, internal RC oscillator and bypass for external clock
• 4 Power Saving Modes: Halt, Active Halt, Wait and Slow

Interrupts
Table 20.
1. In Flash devices only a RESET or MCC/RTC interrupt can be used to wake-up from Active Halt mode.
2. Exit from HALT possible when SPI is in slave mode.
3. Exit from HALT possible when PWM ART is in external clock mode.
