ST7DALI
8-BIT MCU WITH SINGLE VOLTAGE FLASH MEMORY,
DATA EEPROM, ADC, TIMERS, SPI, DALI
Memories
– 8 Kbytes single voltage Flash Program mem-
ory with read-out protection, In-Circuit Pro-
gramming and In-Application programming
(ICP and IAP). 10K write/erase cycles guar-
anteed, data retention: 20 years at 55°C.
– 384 bytes RAM
– 256 bytes data EEPROM with read-out pro-
tection. 300K write/erase cycles guaranteed,
data retention: 20 years at 55°C.
Clock, Reset and Supply Management
– Enhanced reset system
– Enhanced low voltage supervisor (LVD) for
main supply and an auxiliary voltage detector
(AVD) with interrupt capability for implement-
ing safe power-down procedures
– Clock sources: Internal 1% RC oscillator,
crystal/ceramic resonator or external clock
– Internal 32-MHz input clock for Auto-reload
timer
– Optional x4 or x8 PLL for 4 or 8 MHz internal
clock
– Five Power Saving Modes: Halt, Active-Halt,
Wait and Slow, Auto Wake Up From Halt
I/O Ports
– Up to 15 multifunctional bidirectional I/O lines
–7 high sink outputs
4 Timers
– Configurable Watchdog Timer
– Two 8-bit Lite Timers with prescaler, watch-
dog,
1 realtime base and 1 input capture
– One 12-bit Auto-reload Timer with 4 PWM
outputs, input capture and output compare
functions
2 Communication Interfaces
– SPI synchronous serial interface
– DALI communication interface
Interrupt Management
– 10 interrupt vectors plus TRAP and RESET
– 15 external interrupt lines (on 4 vectors)
A/D Converter
– 7 input channels
– Fixed gain Op-amp
– 13-bit resolution for 0 to 430 mV (@ 5V VDD)
– 10-bit resolution for 430 mV to 5V (@ 5V VDD)
