UPSD3254BV-24U6 Datasheet

Microcontrollers - MCU


The UPSD3254BV-24U6 Series combines a fast 8051-based microcontroller with a flexible memory structure, programmable logic, and a rich peripheral mix including USB, to form an ideal embedded controller. At its core is an industry-standard 8032 MCU operating up to 40MHz.A JTAG serial interface is used for In-System Programming (ISP) in as little as 10 seconds, perfect for manufacturing and lab development.The USB 1.1 low-speed interface has one Control endpoint and two Interrupt endpoints suitable for HID class drivers. UPSD3254BV-24U6 Features • Fast 8-bit 8032 MCU 40 MHz at 5.0 V, 24 MHz at 3.3 V Core, 12-clocks per instruction• Dual Flash memories with memory management Place either memory into 8032 program address space or data address space Read-while-write operation for inapplication programming and EEPROM emulation Single voltage program and erase 100,000 minimum erase cycles, 15-year retention• Clock, reset, and supply management Normal, idle, and power down modes Power-on and low voltage reset supervisor Programmable watchdog timer• Programmable logic, general-purpose 16 macrocells Implements state machines, glue-logic, etc.• Timers and interrupts Three 8032 standard 16-bit timers 10 Interrupt sources with two external interrupt pins• A/D converter Four channels, 8-bit resolution, 10 µs• Communication interfaces USB v1.1, low-speed 1.5 Mbps, 3 endpoints I2C master/slave bus controller Two UARTs with independent baud rate Six I/O ports with up to 46 I/O pins 8032 address/data bus available on TQFP80 package 5 PWM outputs, 8-bit resolution• JTAG in-system programming Program the entire device in as little as 10 seconds• Single supply voltage 4.5 to 5.5 V 3.0 to 3.6 V• ECOPACK® packages
