9 / 152 page Power DSP56362 Technical Data, Rev. 4 Freescale Semiconductor 2-3 2.2 Power Table 2-2 Power Inputs Power Name Description VCCP PLL Power—VCCP is VCC dedicated for PLL use. The voltage should be well-regulated and the input should be provided with an extremely low impedance path to the VCC power rail. There is one VCCP input. VCCQL (4) Quiet Core (Low) Power—VCCQL is an isolated power for the core processing logic. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. There are four VCCQ inputs. VCCQH (3) Quiet External (High) Power—VCCQH is a quiet power source for I/O lines. This input must be tied externally to all other chip power inputs. The user must provide adequate decoupling capacitors. There are three VCCQH inputs. VCCA (3) Address Bus Power—VCCA is an isolated power for sections of the address bus I/O drivers. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. There are three VCCA inputs. VCCD (4) Data Bus Power—VCCD is an isolated power for sections of the data bus I/O drivers. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. There are four VCCD inputs. VCCC (2) Bus Control Power—VCCC is an isolated power for the bus control I/O drivers. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. There are two VCCC inputs. VCCH Host Power—VCCH is an isolated power for the HDI08 I/O drivers. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. There is one VCCH input. VCCS (2) SHI, ESAI, DAX, and Timer Power—VCCS is an isolated power for the SHI, ESAI, DAX, and Timer I/O drivers. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. There are two VCCS inputs. |
