New Renesas R8C/Tiny 16-bit Microcontrollers for Electronic Appliances

Renesas is introducing its 30 new products of its R8C/Tiny series 16-bit microcontrollers. The devices in the R8C/2E, 2F, 2G, 2H, 2J, 2K and 2L groups raise the total number of products in the R8C/Tiny series to 268 in 33 groups. The new microcontrollers are designed for electronic appliance applications such as  handheld power tools, motor control and electronic ballast.

Key features.

• R8C/2K and /2L groups have a 32-pin package and provide timer functions that are ideal for motor control - Their on-chip 3-channel 16-bit timer modules have advanced waveform generation capabilities as well as standard input-capture/output-compare functions. A single microcontroller can handle both 3-phase PWM (pulse width modulation) output and 3-phase pulse input for control of brushless DC motors. The timers can operate at 40MHz from a high-precision on-chip oscillator, allowing fast, precise motor control operation.
• R8C/2E and /2F groups are the first 32-pin R8C devices with D/A converter and comparator functions - Their rich set of analog peripheral functions - 8-bit 2-channel D/A converter, 2-channel comparator, and 10-bit 12-channel A/D converter - is tightly coupled and can be configured at runtime for different tasks, making them ideal for applications such as electronic ballast control that require quick and accurate analog processing.
• R8C/2G, /2H, and /2J groups have simpler functionality to reduce cost for applications that don't require certain built-in peripherals - These 20- and 32-pin devices are designed for cost sensitive applications where microcontroller-based electronics replace electromechanical/discrete designs. These microcontrollers provide key value-added on-chip features to reduce overall system cost. They include an 8MHz high-accuracy on-chip oscillator, power-on reset (POR), comparators, and low-voltage detect (LVD).
  All of these devices come with a hardware LIN function that allows connecting multiple devices efficiently at low cost.

Renesas also offers a suite of development tools for R8C/Tiny microcontrollers. Developer can evaluate the microcontrollers using existing starter kits which include an on-chip debug emulator, target board and software tools. The on-chip debug emulator uses a 1-wire interface, leaving all I/O pins available for more efficient program development. For advanced debugging features, low-cost full-function emulators are also available for the 2K and 2L groups. In addition, the Renesas High-performance Embedded Workshop with C/C++ compiler and assembler tools is available free of charge to all users requiring 64KB or less memory.
