S912XEP100W1MAL

Description

The MC9S12XE-Family of micro controllers is a further development of the S12XD-Family including new features for enhanced system integrity and greater functionality. These new features include a Memory Protection Unit (MPU) and Error Correction Code (ECC) on the Flash memory together with enhanced EEPROM functionality (EEE), an enhanced XGATE, an Internally filtered, frequency modulated Phase Locked Loop (IPLL) and an enhanced ATD. The E-Family extends the S12X product range up to 1MB of Flash memory with increased I/O capability in the 208-pin version of the flagship MC9S12XE100.

Features

• 16-Bit CPU12X
— Upward compatible with MC9S12 instruction set with the exception of five Fuzzy instructions (MEM, WAV, WAVR, REV, REVW) which have been removed
— Enhanced indexed addressing
— Access to large data segments independent of PPAGE
• INT (interrupt module)
— Eight levels of nested interrupts
— Flexible assignment of interrupt sources to each interrupt level.
— External non-maskable high priority interrupt (XIRQ)
— Internal non-maskable high priority Memory Protection Unit interrupt
— Up to 24 pins on ports J, H and P configurable as rising or falling edge sensitive interrupts
• EBI (external bus interface)(available in 208-Pin and 144-Pin packages only)
— Up to four chip select outputs to select 16K, 1M, 2M and up to 4MByte address spaces
— Each chip select output can be configured to complete transaction on either the time-out of one of the two wait state generators or the deassertion of EWAIT signal
• MMC (module mapping control)
• DBG (debug module)
— Monitoring of CPU and/or XGATE busses with tag-type or force-type breakpoint requests
— 64 x 64-bit circular trace buffer captures change-of-flow or memory access information
• BDM (background debug mode)
• MPU (memory protection unit)
— 8 address regions definable per active program task
— Address range granularity as low as 8-bytes
— No write / No execute Protection Attributes
— Non-maskable interrupt on access violation
• XGATE
— Programmable, high performance I/O coprocessor module
— Transfers data to or from all peripherals and RAM without CPU intervention or CPU wait states
— Performs logical, shifts, arithmetic, and bit operations on data
— Can interrupt the HCS12X CPU signalling transfer completion
— Triggers from any hardware module as well as from the CPU possible
— Two interrupt levels to service high priority tasks
— Hardware support for stack pointer initialisation
• OSC_LCP (oscillator)
— Low power loop control Pierce oscillator utilizing a 4MHz to 16MHz crystal
— Good noise immunity
— Full-swing Pierce option utilizing a 2MHz to 40MHz crystal
— Transconductance sized for optimum start-up margin for typical crystals
