Renesas H8/36077 microcontrollers (MCUs) are optimized, lower-cost additions to the popular H8/Tiny family of devices. The four devices in this product group have a 20MHz, 16-bit H8/300H CPU core with 32-bit load-store architecture and sixteen 16-bit configurable general registers. Sixty-two 16-bit instructions allow high code density and efficiently support C/C++ programming.

These 5V MCUs free system designers from the limitations of 8-bit devices. They have an extensive set of peripheral functions, provide well-chosen flash and mask-ROM memory options, and are available in 64-pin lead-free QFP (14mm x 14mm) and LQFP (10mm x 10mm) packages — all at prices that fit tight cost budgets.

Specifically, the MCUs in the H8/36077 series provide 32KB or 56 KB of on-chip flash or mask ROM and 4KB of RAM. On-chip peripherals include two 8-bit timers, two 16-bit timers, a watchdog timer, 8-channel 10-bit A/D, 14-bit PWM (D/A), real-time clock, and on-chip oscillator. There are 11 external interrupts and two serial (sync/async) ports plus an I²C channel, as well as 55 GPIO ports and eight high-current I/O ports. For enhanced system reliability, these new members of the H8/Tiny family also provide power-on reset (POR), low-voltage detect (LVD) and oscillator-stop detect (OSD)
functions. Four power-down modes can be used to conserve system power.

H8/36077 Development Tools

Renesas offers extensive development tool support for H8/36077 series MCUs. For example, the H8/36077 development tool kit (SKPH8TINY) has all the hardware and software tools needed to get up and running in C or assembly code. Along with a free complete software tool suite (C compiler, assembler, linker, etc.), this kit includes the Renesas E8 on-chip debug emulator (R0E00008KCE00), target board, high-performance embedded workshop (HEW) IDE with software toolchain, example
firmware and projects, and a quick-start guide, tutorials, user manual and other documentation. This kit, which normally sells for $98, is offered for a limited time for only $50. Tools and expert services are also available from the large community of third-party vendors that support H8-series MCUs.

The Renesas Interactive website (www.renesasinteractive.com) is another resource that supports H8/36077 MCUs. To aid device analysis and evaluation, the H8/Tiny Virtual Lab in this site contains a free remote hardware/software setup that is accessible online from a web browser via a secure communication link. This lab setup is usable without procurement or system installation delay. The training area of the Renesas Interactive website contains courses covering various design aspects
of H8/Tiny MCUs that can be reviewed whenever it is convenient to do so.
