Continuing to proliferate its 16-bit MCUs across as many embedded control markets and applications as possible, Renesas Technology America has added 36 new auto-oriented devices to its portfolio of 148 other devices.
Targeting automotive applications, they have a high-resolution 16-bit timer that can be clocked at high speeds up to 40MHz by a separate on-chip oscillator, and a LIN interface. They offer low-voltage (2.2 to 5.5V) and wide-temperature-range (-40 to +125 degrees C) operation. Devices in the R8C/26 and R8C/27 groups have compact (7 x 7mm) 32-pin LQFP packages, while those in the R8C/28 and R8C/29 groups have even smaller (6.5 x 4.4mm) 20-pin LSSOP packages.
For the R8C/26 and R8C/27 product groups, the on-chip flash memory for program storage is either 32, 24, 16 or 8Kbytes, while for the R8C/28 and R8C/29 groups, it is 16 or 8Kbytes. Moreover, the MCUs in the R8C/27 and R8C/29 groups include an extra 2Kbytes of data flash memory with higher endurance (organized as two 1Kbyte blocks) that can be used for both program and data storage.
They offer a comprehensive range of on-chip peripheral functions, including a high-precision on-chip clock oscillator and a low voltage detection circuit.
According to Ritesh Tyagi, senior marketing manager, system LSI business unit, Renesas Technology America, to simplify the development of LIN-compatible products and reduce the CPU's software processing load, most of the protocol processing is performed by hardware using an 8-bit timer channel and a
synchronous/ UART serial interface channel.
Renesas development tools for the new R8C/26, R8C/27, R8C/28, R8C/29 series devices include the E8 emulator/on-chip debugger with single-pin connection
capability. It allows all I/O pins to be used during debugging, for more efficient program development, and can also be used as a flash memory writer.
The company’s high-performance Embedded Workshop (HEW), an integrated
development environment with a full software toolset is available, too, as are tools and services from the many independent vendors that support the R8C series.
With the introduction of the new devices, Tyagi said Renesas is starting a factory flash programming service with one-time nominal charges. After paying the $1,000 non recurring engineering (NRE) fee, customers do not need to pay additional per device fees.
The minimum order quantity for the free factory programming service is 50,000 pieces per year and the minimum lot for each order is 2,000 pieces.
