Description
ST72F521, ST72521B
80/64-PIN 8-BIT MCU WITH 32 TO 60K FLASH/ROM, ADC, FIVE TIMERS, SPI, SCI, I2C, CAN INTERFACE
■ Memories
– 32K to 60K dual voltage High Density Flash (HDFlash) or ROM with read-out protection capability. In-Application Programming and In-Circuit Programming for HDFlash devices
– 1K to 2K RAM – HDFlash endurance: 100 cycles, data reten-
tion: 20 years at 55°C ■ Clock, Reset And Supply Management
– Enhanced low voltage supervisor (LVD) for main supply and auxiliary voltage detector (AVD) with interrupt capability
– Clock sources: crystal/ceramic resonator oscillators, internal RC oscillator and bypass for external clock
– PLL for 2x frequency multiplication – Four power saving modes: Halt, Active-Halt,
Wait and Slow ■ Interrupt Management
– Nested interrupt controller – 14 interrupt vectors plus TRAP and RESET – Top Level Interrupt (TLI) pin – 15 external interrupt lines (on 4 vectors) ■ Up to 64 I/O Ports
– 48 multifunctional bidirectional I/O lines – 34 alternate function lines – 16 high sink outputs ■ 5 Timers
– Main Clock Controller with: Real time base, Beep and Clock-out capabilities
– Configurable watchdog timer – Two 16-bit timers with: 2 input captures, 2 out-
put compares, external clock input on one timer, PWM and pulse generator modes – 8-bit PWM Auto-Reload timer with: 2 input captures, 4 PWM outputs, output compare and time base interrupt, external clock with event detector
