Introduction
1.1.2 Critical Performance Parameters
The critical performance parameters of the PXR40 feature the following:
⢠Maximum CPU frequency: 264 MHz
â Platform and peripheral modules typically run at half of the CPU frequency
â Some peripheral modules (including the eTPU modules) support a full frequency mode with a
maximum operating frequency of 200 MHz
⢠Temperature range: â40ï° to 105 ï°C
⢠Nominal power dissipation is less than 1.4 W, while enhancements to allow reduced power
operation using clock gating are included
⢠Separate power supply available for stand-by operation of a portion of SRAM
1.1.3 Low-power modes
The PXR40 includes two special modes to allow reduction of application power consumption:
⢠Slow mode: Allows the device to be run at very low speed (approximately 1 MHz), with modules
(including the PLL) selectively disabled by software.
⢠Stop mode: System clock stopped to most modules including the CPU. Wake-up timer used to
restart the system clock after a predetermined time.
1.2 Packages
The PXR40 is offered in a 416-ball PBGA, 1 mm ball pitch, 27 mm ï´ 27 mm outline (no EBI) package
type.
1.2.1 Chip-level features
On-chip modules available within the family include the following features:
⢠Dual issue, 32-bit CPU core complex (e200z7)
â Compliant with the Power Architecture embedded category
â 16 KB I-Cache and 16 KB D-Cache
â Includes an instruction set enhancement allowing variable length encoding (VLE), optional
encoding of mixed 16-bit and 32-bit instructions, for code size footprint reduction
â Includes signal processing extension (SPE2) instruction support for digital signal processing
(DSP) and single-precision floating point operations
⢠4 MB on-chip flash
â Supports read during program and erase operations, and multiple blocks allowing EEPROM
emulation
⢠256 KB on-chip general-purpose SRAM including 32 KB of standby RAM
⢠Two direct memory access controller (eDMA2) blocks
â One supporting 64 channels
