MPT612
Product data sheet
ARM7TDMI-S 32 bit RISC core operating at up to 70 MHz
128-bit wide interface and accelerator enabling 70 MHz operation
10-bit ADC providing
One 32-bit timer and external event counter with four capture and four compare
channels
One 16-bit timer and external event counter with three compare channels
Low power Real-Time Clock (RTC) with independent power supply and dedicated
32 kHz clock input
Serial interfaces including:
Vectored interrupt controller with configurable priorities and vector addresses
Up to twenty eight (28), 5 V tolerant fast general purpose I/O pins
Up to 13 edge or level sensitive external interrupt pins available
Three levels of flash Code Read Protection (CRP)
70 MHz maximum clock available from programmable on-chip PLL with input
frequencies between 10 MHz and 25 MHz and a settling time of 100 ms
Integrated oscillator operates with an external crystal at between 1 MHz and 25 MHz
Power saving modes include:
Individual enabling/disabling of peripheral functions and peripheral clock scaling for
additional power optimization
Processor wake-up from Power-down and Deep power-down mode using an external
interrupt or the RTC
DC application charge controller for solar PV power and fuel-cells. The use cases are
DC-DC converter per panel to provide improved efficiency
Micro inverter per panel removes the need for one large system inverter
Eight analog inputs
Conversion times as low as 2.44 µs per channel and dedicated result registers
minimize interrupt overhead
Five analog inputs available for user specific applications
Two UARTs (16C550)
Two Fast I
SPI and SSP with buffering and variable data length capabilities
Idle mode
Two Power-down modes; one with the RTC active and with the RTC deactivated
Battery charging for home appliances such as lighting, DC fans, DC TV,DC motor
or any other DC appliance
Battery charging for public lighting and signaling - LED street lighting,
garden/driveway lighting, railway signaling, traffic signaling, remote telecom
terminals/towers etc
Battery charging for portable devices
