16 Bit Microcontroller | NXP Semiconductors

Overview

(*This product is on end-of-life. Last shipments are being made through February, 2003.)

The 68HC916R1 is a high-speed 16 bit control unit that combines high-performance data manipulation capabilities with powerful peripheral subsystems and is upwardly code compatible with the 68HC11 Family of microcontrollers. This MCU is built up from standard modules that interface through a common intermodule bus (IMB).

The 68HC916R1 incorporates a true 16 bit central processing unit (CPU), a single chip integration module 2 (SCIM2), an 8/10 bit analog-digital converter (ADC), a multichannel communication interface (MCCI), a Configurable Timer Module 7 (CTM7), a 2 Kbyte static standby RAM module (SRAM), a 2 Kbyte block-erasable flash EEPROM (BEFLASH) and a 48 Kbyte flash EEPROM module (FLASH).

The 68HC916R1 has special features that facilitate emulation of the 68HC16R1.
