Energy metering IC
Serial interfaces:
UART with fractional baud rate generation, internal FIFO, and RS-485 support.
One SPI controller with SSP features and with FIFO and multi-protocol capabilities.
I2C-bus interface supporting full I2C-bus specification and Fast-mode Plus with a
data rate of 1 Mbit/s with multiple address recognition and monitor mode.
Clock generation:
12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used
as a system clock.
Crystal oscillator with an operating range of 1 MHz to 25 MHz.
Programmable watchdog oscillator with a frequency range of 7.8 kHz to 1.8 MHz.
PLL allows CPU operation up to the maximum CPU rate without the need for a
high-frequency crystal. May be run from the system oscillator or the internal RC
oscillator.
Clock output function with divider that can reflect the system oscillator clock, IRC
clock, CPU clock, and the Watchdog clock.
Power control:
Integrated PMU (Power Management Unit) to minimize power consumption during
Sleep, Deep-sleep, and Deep power-down modes.
Three reduced power modes: Sleep, Deep-sleep, and Deep power-down.
Processor wake-up from Deep-sleep mode via a dedicated start logic using up to
13 of the functional pins.
Power-On Reset (POR).
Brownout detect with four separate thresholds for interrupt and forced reset.
Unique device serial number for identification.
Single 3.3 V power supply (1.8 V to 3.6 V).
Available as 33-pin HVQFN33 package.
