The 16 devices, members of the Tiny Series, are designed specifically to reduce the size and system cost of door modules, airbag controllers, shock absorber shock absorber, device for reducing the effect of a sudden shock by the dissipation of the shock's energy. On an automobile, springs and shock absorbers are mounted between the wheels and the frame.  controllers, anti-theft devices and other electronics modules that are networked to protect safety and body-control systems in the vehicle.

Eight of the MCUs are in the H8/36057 series; the other eight are in the H8/36037 series. Four are F-ZTAT(TM) MCUs that offer up to 56 kilobytes (56KB) of on-chip flash memory for in-circuit programmability, while the remaining 12 have up to 56KB of mask ROM (mask Read Only Memory) Refers to ROM chips. The term is used to differentiate static ROM chips from programmable ROM varieties (EPROM, EEPROM, flash ROM). See ROM.  for lower cost.

Facilitating Interconnected Automotive Systems See ITS, embedded system, drive-by-wire, adaptive cruise control, collision avoidance system, autonomous vehicle, heads-up display, DSRC, lane departure system, CAN bus, FlexRay and SYNC.

The design trend in automotive applications is to interconnect the different in-vehicle electronics modules. Sensors talk to one or more controllers that exchange information and drive actuators that provide feedback for precise, closed-loop control. To provide the connectivity cost-effective networked designs require, the economical H8/36057 and H8/36037 series MCUs support four communication functions.

The MCUs include a Tiny HCAN HCAN Hockey Canada (governing body of Canadian hockey)  (Hitachi CAN) function, a full CAN-compatible, 4-message-buffer network controller that complies with the Bosch CAN Ver. 2.0B active specification. They also support the LIN, an in-vehicle, low-speed network (20,000 bits per second) for switching or operating systems Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. . The H8/36057 and H8/36037 series chips can be used as the master controller in a LIN installation or as one of the up to 15 slave processors. For automotive applications, drivers for the CAN and LIN interfaces are available. The MCUs also have an on-chip serial communication interface (SCI (Scalable Coherent Interface) An IEEE standard for a high-speed bus that uses wire or fiber-optic cable. It can transfer data up to 1GBytes/sec.

The H8/36037 MCUs have one SCI channel, whereas the H8/36057 devices have two. They also provide a 4-wire synchronous serial communication unit (SSU SSU Small Subunit

Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting.  or sensor.

Features That Help Reduce System Cost

To allow system engineers to choose the most economical MCU for a particular application to reduce system cost, Renesas offers a variety of memory sizes in each of the new series. The F-ZTAT MCUs have either 56KB or 32KB of flash. Other versions have 56KB, 48KB, 40KB, 32KB, 24KB, or 16KB of mask ROM. The on-chip flash memory can be programmed and erased using a single power supply. This capability enables control programs, system adjustment data, and the like to be rewritten on-board, for shorter system development times and in-field software updates.

The H8/36057 and H8/36037 MCUs provide key on-chip peripherals that help reduce system cost. Besides the previously mentioned CAN, LIN and SCI functions, they have sophisticated timers, a 10-bit A/D converter (Analog/Digital converter) A device that converts continuously varying analog signals from instruments and sensors that monitor conditions, such as sound, movement and temperature into binary code for the computer. , and high-current pins.

For applications that require protection from power supply voltage fluctuations, power-on reset A power-on reset (PoR) generator is a microcontroller or microprocessor peripheral that generates a reset signal when power is applied to the device. It ensures that the device starts operating in a known state.  (POR POR problem-oriented record.

) functions are available as options, reducing the external parts needed.

RC Oscillator, Subtimer Decrease System Power Consumption

The MCUs integrate the system clock oscillation circuit used for full-speed operation. They also provide an RC (resister capacitor) oscillation circuit for use as a low-speed subclock, and a subtimer that operates on this subclock. These circuits are useful in an application such as a keyless entry system, in which the system clock, CPU CPU

, and peripheral modules are halted in module standby mode and only the subtimer operates, activating the CPU periodically. To minimize power dissipation, the device has four power-saving modes: sleep, standby, subsleep and subactive.

In addition to the existing E10T on-chip debugger emulator, Renesas is offering a new upward compatible E7 emulator. The E7 emulator is an upgraded version of the E10T and supports a USB USB

These tools allow program debugging to be carried out with the MCU mounted on a circuit board. The wide range of tools available for H8 Tiny Series devices can also be used to develop embedded systems that apply the new MCUs.
