S6E1C3 Series
32-bit ARM® Cortex®-M0+ FM0+ Microcontroller
The S6E1C3 Series is a series of highly integrated 32-bit microcontrollers designed for embedded controllers aiming at low power consumption and low cost. This series has the ARM Cortex-M0+ Processor with on-chip Flash memory and SRAM, and consists of peripheral functions such as various timers, ADC and communication interfaces (UART, CSIO (SPI), I2C, I2S, Smart Card, and USB). The products which are described in this data sheet are placed into TYPE3-M0+ product categories in "FM0+ Family Peripheral Manual".
Features

S6E1C3 Series
I2C Slave
I2C Slave supports the slave function of I2C and wake-up function from Standby mode.
Descriptor System Data Transfer Controller (DSTC) (64 Channels) The DSTC can transfer data at high-speed without going via
the CPU. The DSTC adopts the Descriptor system and, following the specified contents of the Descriptor that has already been constructed on the memory, can access directly the memory / peripheral device and performs the data transfer operation.
It supports the software activation, the hardware activation, and the chain activation functions
A/D Converter (Max: 8 Channels)
12-bit A/D Converter Successive approximation type Conversion time: 2.0 μs @ 2.7 V to 3.6 V Priority conversion available (2 levels of priority) Scan conversion mode Built-in FIFO for conversion data storage (for scan conversion: 16 steps, for priority conversion: 4 steps)
Base Timer (Max: 8 Channels) The operation mode of each channel can be selected from one of the following.
16-bit PWM timer
16-bit PPG timer
16/32-bit reload timer
16/32-bit PWC timer
General-Purpose I/O Port This series can use its pin as a general-purpose I/O port when it is not used for an external bus or a peripheral function. All ports can be set to fast general-purpose I/O ports or slow general-purpose I/O ports. In addition, this series has a port relocate function that can set to which I/O port a peripheral function can be allocated.
All ports are Fast GPIO which can be accessed by 1cycle
Capable of controlling the pull-up of each pin
Capable of reading pin level directly
Port relocate function
Up to 54 fast general-purpose I/O ports @64-pin packa.
