XPC850DEZT50BU General Description

NXP Semiconductors presents the XPC850DEZT50BU microcontroller, a powerful member of the XPC850 family designed to address the demanding requirements of industrial and automotive applications. With its PowerPC core operating at a maximum frequency of 50 MHz and on-chip cache memory, this microcontroller delivers enhanced processing power and efficiency. Its comprehensive set of communication interfaces, including CAN, UART, I2C, and SPI, provides flexible connectivity options for interfacing with different systems and devices. Additionally, the XPC850DEZT50BU is equipped with a diverse range of peripherals such as timers, GPIOs, and analog-to-digital converters, facilitating seamless integration with external devices and sensors. The inclusion of a memory management unit (MMU) ensures efficient memory access and protection, while built-in support for real-time operating systems (RTOS) further enhances its performance in real-time applications

Key Features

The following list summarizes the key MPC860
features:
Embedded single-issue, 32-bit MPC8xx core (implementing the PowerPC architecture) with thirty-two 32-bit general-purpose registers (GPRs)
— The core performs branch prediction with conditional prefetch, without conditional execution
— 4- or 8-Kbyte data cache and 4- or 16-Kbyte instruction cache (see Table 1)
– 16-Kbyte instruction caches are four-way, set-associative with 256 sets;
4-Kbyte instruction caches are two-way, set-associative with 128 sets.
– 8-Kbyte data caches are two-way, set-associative with 256 sets; 4-Kbyte data caches are two-way, set-associative with 128 sets.
– Cache coherency for both instruction and data caches is maintained on 128-bit (4-word) cache blocks.
– Caches are physically addressed, implement a least recently used (LRU) replacement algorithm, and are lockable on a cache block basis.
— Instruction and data caches are two-way, set-associative, physically addressed, LRU replacement, and lockable on-line granularity.
— MMUs with 32-entry TLB, fully associative instruction, and data TLBs
— MMUs support multiple page sizes of 4, 16, and 512 Kbytes, and 8 Mbytes; 16 virtual address spaces and 16 protection groups
— Advanced on-chip-emulation debug mode
Up to 32-bit data bus (dynamic bus sizing for 8, 16, and 32 bits)
32 address lines
Operates at up to 80 MHz
Memory controller (eight banks)
— Contains complete dynamic RAM (DRAM) controller
— Each bank can be a chip select or RASto support a DRAM bank
— Up to 15 wait states programmable per memory bank
— Glueless interface to DRAM, SIMMS, SRAM, EPROM, Flash EPROM, and other memory devices.
— DRAM controller programmable to support most size and speed memory interfaces
— Four CASlines, four WElines, one OEline
— Boot chip-select available at reset (options for 8-, 16-, or 32-bit memory)
— Variable block sizes (32 Kbyte to 256 Mbyte)
— Selectable write protection
— On-chip bus arbitration logic
General-purpose timers
— Four 16-bit timers or two 32-bit timers
— Gate mode can enable/disable counting
— Interrupt can be masked on reference match and event capture
System integration unit (SIU)
— Bus monitor
— Software watchdog
— Periodic interrupt timer (PIT)
— Low-power stop mode
— Clock synthesizer
— Three parallel I/O registers with open-drain capability
Four baud-rate generators (BRGs)
— Independent (can be connected to any SCC or SMC)
— Allow changes during operation
— Autobaud support option
Four serial communications controllers (SCCs)
— Ethernet/IEEE 802.3 optional on SCC1–4, supporting full 10-Mbps operation (available only on specially programmed devices).
— HDLC/SDLC(all channels supported at 2 Mbps)

— Asynchronous HDLC to support PPP (point-to-point protocol)
— AppleTalk
— Universal asynchronous receiver transmitter (UART)
— Synchronous UART
— Serial infrared (IrDA)
— Binary synchronous communication (BISYNC)
— Totally transparent (bit streams)
— Totally transparent (frame based with optional cyclic redundancy check (CRC))
Two SMCs (serial management channels)
— UART
— Transparent
— General circuit interface (GCI) controller
— Can be connected to the time-division multiplexed (TDM) channels
One SPI (serial peripheral interface)
— Supports master and slave modes
— Supports multimaster operation on the same bus
One I2C (inter-integrated circuit) port
— Supports master and slave modes
— Multiple-master environment support
Time-slot assigner (TSA)
— Allows SCCs and SMCs to run in multiplexed and/or non-multiplexed operation
— Supports T1, CEPT, PCM highway, ISDN basic rate, ISDN primary rate, user defined
— 1- or 8-bit resolution
— Allows independent transmit and receive routing, frame synchronization, clocking
— Allows dynamic changes
— Can be internally connected to six serial channels (four SCCs and two SMCs)
Parallel interface port (PIP)
— Centronics interface support
— Supports fast connection between compatible ports on the MPC860 or the MC68360
PCMCIA interface
