Epson Shipping Samples of New 16-Bit Flash Microcontroller- S1C17M40 supports products from home appliance remote controllers tocompact factory automation devices, including those requiring 5V operation -

Seiko Epson Corporation (TSE: 6724, "Epson") has begun shipping samples of the newly developed
S1C17M40, a low-power microcontroller with 16-bits of embedded flash memory. This microcontroller
unit (MCU) is ideal for remote controlled home appliances such as air conditioners and for small factory
automation devices such as time switches and counters. The company plans to produce 200,000 units
per month.

S1C17M40 key product features
Like the other MCUs in the S1C17M3 series, the new S1C17M40 is a versatile MCU with specifications
that are ideal for liquid crystal displays. The S1C17M40 also has an embedded oscillator circuit that is
stable to within ±1% over an operating temperature range of 0°C to 85°C, an improvement over the
±1% of the S1C17M3 at an operating temperature of 25°C. Moreover, the S1C17M40 is Epsonʼs first
single-chip MCU with embedded EEPROM.


Embedded circuits that will reduce the number of components in customersʼ products, save
board space, and shrink software development times
- Embedded oscillator stability: ±1% (when operating at 16 MHz in an operating temperature range
of 0-85°C
- Embedded EEPROM (electrically erasable programmable read-only memory)
- Supply voltage detector (SVD) circuit that does not require an external power supply supervisor
- Real-time clock
- Analog-digital converter
- A universal port multiplexer (UPMUX) that allows software to select the input/output function to
be assigned to each port
- Three types of serial communications interfaces
- Generator circuit for infrared remote-control output signal
Low-voltage and low-current consumption that extend battery life
- Guaranteed operating range: 1.8 V - 5.5V
- Current consumption in SLEEP mode: 0.25µA
- Power consumption in RUN mode: 170µA/MHz


Summary
Epsonʼs single-chip MCUs, which integrate low-power and liquid crystal driving technologies, have
earned a strong reputation among customers for applications in a variety of small devices. A growing
number of MCUs support only low operating voltages, but there is still a strong need in factory
automation equipment and some home appliances for MCUs that support 5 V operation. So, in 2017,
Epson began volume-producing the S1C17M3 series of MCUs with selectable operating voltages
ranging from 1.8 V to 5.5 V. The new S1C17M40 is considered the next-generation model in the
S1C17M3 series, which is part of Epsonʼs expanding S1C17 family of MCUs with 16-bits of embedded
flash memory。
