3ꢃ-bit ARM^®Cortex™-M3 MCU

HT3ꢃF1656/HT3ꢃF1655

Features

Core

32-bit ARM^®Cortex™-M3 processor core

▀

Up to 72 MHz operating frequency

1.25 DMIPS/MHz (Dhrystone 2.1)

Single-cycle multiplication and hardware division

Integrated Nested Vectored Interrupt Controller (NVIC)

24-bit SysTick timer

The Cortex™-M3 processor is a general-purpose 32-bit processor core especially suitable for

products requiring high performance and low power consumption microcontrollers. It offers many

special features such as a Thumb-2 instruction set, hardware divider, low latency interrupt respond

time, atomic bit-banding access and multiple buses for simultaneous accesses. The Cortex™-M3

processor is based on the ARMv7 architecture and supports both Thumb and Thumb-2 instruction

sets.

On-chip Memory

Up to 256 KB on-chip Flash memory for instruction/data and option storage

▀

32 KB on-chip SRAM

Supports multiple boot modes

The ARM^®Cortex™-M3 processor is structured using Harvard architecture which uses a separate

bus structure to fetch instructions and load/store data. The instruction code and data are both

located in the same memory address space but in different address ranges. The maximum address

range of the Cortex™-M3 is 4 GB due to its 32-bit bus address width. Additionally, a pre-deﬁned

memory map is provided by the Cortex™-M3 processor to reduce the software complexity of

repeated implementation for different device vendors. However, some regions are used by the

ARM^®Cortex™-M3 system peripherals. Refer to the ARM^®Cortex™-M3 Technical Reference

Manual for more information. Figure 2 shows the memory map of the HT32F1656/55 series of

devices, including Code, SRAM, peripheral, and other pre-deﬁned regions.

Flash Memory Controller

Flash accelerator for maximum efﬁciency

▀

32-bit word programming with In System Programming Interface (ISP) and In Application

Programming (IAP)

▀

Flash protection capability to prevent illegal access

▀

The Flash Memory Controller, FMC, provides all the necessary functions and pre-fetch buffer

for the embedded on-chip Flash Memory. Since the access speed of the Flash Memory is slower

than the CPU, a wide access interface with a pre-fetch buffer and cache are provided for the Flash

Memory in order to reduce the CPU waiting time which will cause CPU instruction execution

delays. Flash Memory word program/page erase functions are also provided.
