GENERAL DESCRIPTION
32-bit Arm® Cortex®-M4 MCU HT32F49153/HT32F49163 1 GENERAL DESCRIPTION
The devices incorporate high-speed on-chip memories, including up to 256 Kbytes of Flash memory, 48 Kbytes of SRAM, and 20 Kbytes of boot memory that can be used as a Bootloader or as a general instruction/data memory (one-time-configurable) to achieve the maximum of 256+20 Kbytes. Any block of the embedded Flash memory can be protected by the “sLib” (security library), functioning as a security area with code-executable only. In addition, the devices include a highlevel memory extension: an external memory controller (XMC). The devices offer one 12-bit ADC, two 12-bit DACs, eight general-purpose 16-bit timers plus one general-purpose 32-bit timer, two basic timers, one advanced timer and one low-power ERTC. It also features standard and advanced communication interfaces: up to three I2Cs, three SPIs (multiplexed as I2Ss), eight USARTs, two CANs, an OTGFS, and infrared transmitter. The devices operate in the -40 to +105 °C temperature range, from a 2.4 to 3.6 V power supply.
