NXP MC68HC908QT1CDW

MC68HC908QT1CDW Description

The MSP430G2453IPW28 is an 8-bit microcontroller that belongs to the high-performing, low-cost m68hc08 family (mcus). A sophisticated instruction-set computer (cisc) having a von Neumann architecture is the m68hc08 series. All of the mcus in the series employ the improved m68hc08 central processing unit (cpu08), and they come in a range of packaging formats, memory capacities, and module options.
