Manufacturer: STMicroelectronics

Overview

ST72324J/K 8-BIT MCU WITH NESTED INTERRUPTS, FLASH, 10-BIT ADC, 4 TIMERS, SPI, SCI INTERFACE PRELIMINARY DATA Memories – 8 to 32K dual voltage High Density Flash (HDFlash) or ROM with read-out protection capability.

In-Application Programming and InCircuit Programming for HDFlash devices – 384 to 1K bytes RAM – HDFlash endurance: 100 cycles, data retention: 20 years at 55°C s Clock, Reset And Supply Management – Enhanced low voltage supervisor (LVD) for main supply with 3 programmable reset thresholds and auxiliary voltage detector (AVD) with interrupt capability – Clock sources: crystal/ceramic resonator oscillators, internal or external RC oscillator, clock security system and bypass for external clock – PLL for 2x frequency multiplication – Four Power Saving Modes: Halt, Active-Halt, Wait and Slow s Interrupt Management – Nested interrupt controller – 10 interrupt vectors plus TRAP and RESET – 9/6 external interrupt lines (on 4 vectors) s Up to 32 I/O Ports – 32/24 multifunctional bidirectional I/O lines – 22/17 alternate function lines – 12/10 high sink outputs s 4 Timers – Main Clock Controller with: Real time base, Beep and Clock-out capabilities – Configurable watchdog timer – 16-bit Timer A with: 1 input capture, 1 output compare, external clock input, fixed freq.

PWM and pulse generator modes – 16-bit Timer B with: 2 input captures, 2 output compares, variable freq.
