The ST72F324BJ6B6 can operate from -40°C to 85°C (industrial temperature range) and from -40°C to 105°C (extended temperature range) with some limitations.
The ST72F324BJ6B6 has an internal RC oscillator, an external clock input, and a PLL (Phase-Locked Loop) for clock multiplication. The clock source can be selected using the CKSEL fuses or through software using the Clock Control Register (CKCU).
The internal RC oscillator can operate up to 16 MHz, but the maximum frequency depends on the voltage supply and temperature range.
The ST72F324BJ6B6 has a 128 KB flash memory that can be programmed using the In-System Programming (ISP) interface, the In-Circuit Serial Programming (ICSP) interface, or through the JTAG interface using a programmer or a development tool like the STMicroelectronics ST-Link.
The power consumption of the ST72F324BJ6B6 depends on the operating frequency, voltage supply, and peripherals used. In active mode, the typical current consumption is around 10 mA at 16 MHz and 3.3 V, while in sleep mode, it can be as low as 10 μA.
