Renesas Technology Introduces 32MHz 16-Bit MCUs with On-Chip Flash Memory and Enhanced Peripherals for Automotive Body and Chassis Control Applications

MCUs in the M16C/5L and M16C/56 groups offer 60 percent faster speeds and more on-chip functions, providing improved performance and reduced system cost

BOSTON — October 27, 2008 — Embedded Systems Conference Boston — Renesas Technology America, Inc. today introduced 14 new 16-bit CISC-type microcontrollers (MCUs) in the M16C/5L and M16C/56 groups. These versatile devices allow improved performance and greater functionality in automotive body and chassis control systems. The company also announced preliminary details of the M16C/5M group, now in development.

The new MCUs are members of the M16C/Tiny series in the M16C family, and are successors to the devices in the M16C/28 and M16C/29 groups. Devices in the M16C/5L group include an on-chip CAN1 controller, while those in the M16C/56 group do not. All of them offer enhanced functionality and performance and integrate a full complement of on-chip peripheral functions that helps reduce the system parts count and size, as well as overall cost.

Because the products in the M16C/5L and M16C/56 groups are compatible with the devices in the M16C/28 and M16C/29 groups, they provide a flexible path for quickly implementing system feature expansions or version upgrades.

Offering designs optimized for high reliability

MCUs in the extensive Renesas M16C family are designed to be highly reliable. They incorporate EMI (electromagnetic interference) and EMS (electromagnetic susceptibility) measures to prevent system malfunctions in electrically noisy environments, provide security functions, offer low power consumption, and have excellent ROM code efficiency. Renesas has continually expanded this family in response to demand from system developers for better performance and functionality.

The new devices in the M16C/5L and M16C/56 groups bring improved functionality and performance to the M16C/Tiny series, yet allow customers to continue utilizing existing system engineering resources. Within short development cycles, engineers can use the latest Renesas devices to create new and upgraded designs that have better functions and performance.

The maximum operating frequency of the devices in both groups is 32MHz, 60 percent faster than the 20MHz (3.0V to 5.5V) of the earlier MCUs. Their 64-pin and 80-pin packages provide pin and peripheral-function compatibility that simplifies updating the functions and performance of system designs that use M16C/28 and M16C/29 MCUs.

Providing three different areas of flash memory, many built-in peripherals

All products in the M16C/5L and M16C/56 groups have on-chip flash memory. Devices in the 80-pin package are available with 96KBytes, 128KBytes, or 256KBytes of flash memory, and those in the 64-pin package are available with capacities of 64KBytes, 96KBytes, 128KBytes, or 256KBytes. The 256Kbyte flash MCUs integrate twice the flash memory previously offered, and thus can accommodate larger programs that take advantage of enhanced functions.

All M16C/5L and M16C/56 MCUs also have 16KBytes of independent user flash memory suitable for storing small-size programs for tasks such as flash rewriting. To help reduce the need for external memory, they also include 8KBytes of data flash memory in two blocks of 4KBytes each, rated to withstand 10,000 rewrite cycles. This special on-chip flash memory can be used for storing data, replacing external EEPROM devices.

Compared to the previous-generation MCUs, the devices in the M16C/5L and M16C/56 groups provide additional on-chip functions as well as others with increased capabilities. For instance, besides the data flash, a precision high-speed clock oscillator has been added and a task monitor timer is now included for managing task processing times. The higher-functionality watchdog timer can run from a dedicated on-chip oscillator. Also, the real-time clock has the ability to count durations from one second to one week.

Additionally, the new MCUs have other built-in functions that reduce the size, complexity and cost of automotive control applications. Examples include timers for three-phase motor control; timers with support for input capture, output compare, and PWM output; a serial-communication interface; a fast A/D converter, and an on-chip debug function. Devices in the M16C/5L group also provide a CAN controller.

Incorporating other features that facilitate system design

The new MCUs give system engineers several ways to save energy. When high-speed operation is needed, power consumption can be reduced by using the high-speed on-chip oscillator instead of the external clock circuit. Whenever less computing throughput is needed and full-speed operation is not necessary, more power can be saved by using power-down (low-power-consumption) modes such as the low-speed Subclock or the Wait mode.

To provide reliability in the harsh environments that characterize many automotive applications, the M16C/5L and M16C/56 devices specify an operating temperature range of -40°C to +85°C. High-temperature versions with an extended operating range of -40°C to +125°C are also available.

System development environments for the new devices include the E8a on-chip debugging emulator, which has flash programming capabilities, and the affordably priced E100 full-spec emulator.

Announcing the M16C/5M group, now in the development stage

Renesas Technology’s future plans for the M16C/Tiny series include the addition of 16 devices in the M16C/5M group, with sample shipments scheduled in the third quarter of 2009. These devices will increase the number of CAN channels, integrate a LIN2 interface, offer improved data flash (100,000 rewrite-cycle capability) for data storage. They will be offered in three packages (64-pin, 80-pin, and 100-pin LQFPs) that are compatible with earlier MCUs.
