Product catalog summary

Introduction
The RX100 series is a new entry-level 32-bit microcontroller (MCU) from Renesas, designed to extend the RX family to the lower end of the spectrum in terms of pin count and flash memory size. It offers high performance at a low cost, featuring True Low Power, fast wake-up, zero wait state flash, and integrated USB 2.0 support.

Specifications
The RX111 group within the RX100 series is notable for its ultra-low-power consumption, consuming only 350 nA in sleep mode and waking up in 4.8 μs. It supports a range of applications including mobile healthcare, smart meters, and industrial automation. Memory sizes range from 16 KB to 128 KB, with packages starting at 36 pins.

Applications
The RX100 MCUs are suitable for various applications such as environmental sensors, home appliances, portable electronics, industrial/commercial systems, building automation, and portable medical devices.

Key Features

Low Power and Fast Wakeup: Consumes 350 nA in standby with a 4.8 μs wake-up time.
USB Connectivity: Supports host, device, and OTG modes.
High Performance: Achieves 3.08 CoreMark/MHz and 50 DMIPS at 32 MHz.
Safety Features: Includes Clock Accuracy Control, Oscillation Stop Detection, Data Operation Circuit, and Independent Watchdog Timer.
Scalability: Fully compatible with RX600 and RX200 series, offering low pin count and multifunction pin controller.

Performance and Power Consumption
The RX100 series offers True Low Power without compromising performance, with multiple operational and sleep modes to minimize power consumption. It features a flexible clock system and three operating modes: high speed, middle speed, and low speed.

Comprehensive On-chip Peripherals
The RX100 MCUs integrate various peripherals to save cost and reduce power consumption, including a 12-bit ADC, 16-bit timers, and a flexible DMA engine.

Portfolio and Compatibility
The RX100 series is the lowest cost product line in the RX family, with the RX111 group offering ultra-low-power operation and USB connectivity. It is compatible with other RX series, providing a wide range of options for different application needs.

Development Tools and Support
Renesas offers a range of development tools including the RX111 Renesas Promotion Board and Starter Kit, along with third-party solutions for RTOS and USB support.

Introduction to RX Ecosystem
Renesas provides a comprehensive suite of hardware and software tools designed to facilitate the development of RX-based systems. These tools aim to streamline the product development process from initial concept to final design.

e2studio IDE
The e2studio is an Eclipse-based Integrated Development Environment (IDE) from Renesas, offering a complete development and debugging environment. It supports both the Renesas Compiler and a free GNU compiler, with features such as software breakpoints, variable and expression views, and advanced debugging capabilities like real-time memory and expression views.

Renesas Customizable Software Library
This library is designed to showcase the RX111 low power modes and includes connectors for Pmod and energy harvesting. It features an integrated J-Link debugger, built-in power measurement, and comes with the e2studio toolchain and USB demo.

Compilers
The IAR Embedded Workbench for RX is available in two editions: the EWRX Standard and the EWRX-8L Baseline edition, the latter being suitable for RX MCUs with smaller memory. A free 64 KB size-limited Kickstart version is also available.

Debugging Tools
On-chip debugging is facilitated via a debug connection to the target and a USB connection to the IDE. The Renesas E1 and E20 debuggers provide comprehensive CPU control and visibility.
