ST72264G2 STMicroelectronics, ST72264G2 Datasheet - Page 9

• Manufacturer Part Number: ST72264G2
• Description: 8-bit MCU
• Manufacturer: STMicroelectronics

Specifications of ST72264G2

• 4 K Or 8 Kbytes Program Memory: ROM or single voltage extended Flash (XFlash) with read-out protection, write protection, In-Circuit Programming and In-Application Programming (ICP and IAP). 10K write/erase cycles guaranteed, data retention
• Clock Sources: crystal/ceramic resonator oscillators, internal RC oscillator and bypass for external clock
• 4 Power Saving Modes: Halt, Active Halt,Wait and Slow
• Two 16-bit Timers With: 2 input captures, 2 output compares, external clock input on one timer, PWM and Pulse generator modes

Notes:
1. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up
column (wpu) is merged with the interrupt column (int), then the I/O configuration is a pull-up interrupt in-
put, otherwise the configuration is a floating interrupt input. Port C is mapped to ei0 or ei1 by option byte.
2. In the open drain output column, “T” defines a true open drain I/O (P-Buffer and protection diode to V
are not implemented). See
3. OSC1 and OSC2 pins connect a crystal or ceramic resonator, or an external source to the on-chip os-
cillator see
