UPSD3253B-40T6 Product Details

UPSD3253B-40T6 Overview


The package is 52-LQFP-shaped. There are 37 I/Os. In the case of the IC chip, the type of mounting is Surface Mount. Microcontroller is based on the 8-Bit core architecture. The type of program memory it uses is FLASH. Temperatures in the range of -40°C~85°C TA are operated by this Microcontroller. It is part of the μPSD series of electrical components. Having a size of 160KB 160K x 8, Microcontroller has a program memory of X bytes. A 8032 Core Processor is at the core of this Microcontroller. This device belongs to the MICROCONTROLLER uPs/uCs/Peripheral ICs category. IC Chip 52 has 52 terminations. 8-bits are used for its size. IC Chip has 5V volt supply outputs. With NO DMA channels, Microcontroller chip can handle large data transfers. 160kB is the size of the memory in the IC part. Using the base part number UPSD32, you will be able to find alternatives for the part. Using a 40MHz frequency, this electronic part can perform efficiently. Devices work in YES PWM channels. On the chip, 52 pins are accessible. In total, there are 3 timers/counters on the device. The pin count is 52. There is an embedded the 8051 CPU family inside the device, which makes it a powerful device.
