NXP Semiconductors MPC8241LZQ200D

Overview

MPC8241LZQ200D from Freescale Semiconductor is a 32-bit PowerPC™ MPC603e-based integrated processor combining a superscalar CPU core with PCI bridge, memory controller, DUART, DMA, and I²C peripherals - operating at up to 200 MHz CPU frequency, 100 MHz memory bus, and 66 MHz PCI clock, deployed in telecom control planes and industrial embedded systems requiring deterministic I/O and legacy PCI peripheral integration.

For engineers reviewing the MPC8241LZQ200D datasheet, MPC8241LZQ200D pinout, MPC8241LZQ200D application, or MPC8241LZQ200D equivalent, this page delivers verified electrical specs, thermal limits, PLL configuration constraints, memory interface timing, and PCI 2.2-compliant signaling behavior - all confirmed against Freescale's MPC8241EC Rev. 10 hardware specification and ordering documentation.

Technical Context

The MPC8241LZQ200D integrates a statically designed 0.25 µm CMOS MPC603e core (16-Kbyte instruction + 16-Kbyte data cache, FPU, MMU) with a dedicated peripheral logic block containing PCI 2.2 interface, SDRAM controller supporting up to 2 Gbytes, dual UARTs, I²C master/slave, and message unit with I2O support. Core and peripheral logic operate on independent PLLs synchronized via shared reference clock.

It implements a decoupled 32-bit address / 64-bit data peripheral logic bus with store-gathering, full coherency, and snoop-enabled PCI-to-processor memory access. Memory interface supports programmable SDRAM timing, ECC/parity, and LVTTL I/O with 3.3 V or 5.0 V PCI tolerance - validated for 200 MHz CPU operation under 0–105°C junction temperature.

FAQ

What is the maximum supported SDRAM capacity for the MPC8241LZQ200D?

The MPC8241LZQ200D supports up to 2 Gbytes of SDRAM memory across one to eight banks, using 16-, 64-, 128-, 256-, or 512-Mbit devices. This is achieved via its 32- or 64-bit wide memory data bus and programmable SDRAM timing registers. The MPC8241LZQ200D datasheet (Section 3, Features) confirms this limit applies to all speed grades including the 200 MHz variant.

Does the MPC8241LZQ200D support both 3.3 V and 5.0 V PCI signaling?

Yes, the MPC8241LZQ200D is PCI 2.2-compliant and 5.0-V tolerant on PCI inputs when LVDD = 5.0 V ± 5%. It also operates with LVDD = 3.3 V ± 0.3 V for 3.3-V signaling. Input thresholds scale accordingly: VIH = 0.65 × GVDD_OVDD for PCI pins, and absolute max ratings allow PCI inputs up to 5.75 V when LVDD = 5 V. This dual-voltage capability is documented in Table 2 and Table 3 of the MPC8241EC Rev. 10 specification.

What power-saving modes does the MPC8241LZQ200D implement, and what are their typical power draws?

The MPC8241LZQ200D implements doze, nap, and sleep modes with typical power consumption of 0.8 W (doze), 0.4 W (nap), and 0.3 W (sleep) at 200 MHz CPU frequency, per Table 5 in the MPC8241EC Rev. 10 spec. These modes reduce dynamic power by gating clocks to non-essential blocks while preserving register state and memory contents - critical for fast wake-up in telecom control plane applications.

Is the MPC8241LZQ200D pin-compatible with other members of the MPC824x family?

Yes, the MPC8241LZQ200D shares identical 357-ball PBGA pinout and register-level compatibility with MPC8241LZQ166D and MPC8245LZQ266D. All three use the same mechanical footprint, signal assignment, and memory-mapped peripheral layout. This enables drop-in replacement across speed grades without PCB redesign - confirmed in Freescale's ordering information (Section 8) and package description (Section 5).

How is DDR or DDR2 memory supported on the MPC8241LZQ200D?

The MPC8241LZQ200D does not support DDR or DDR2 memory. Its memory controller is explicitly designed for SDR SDRAM only, as stated in Section 2 ("Features") and Section 3 ("General Parameters") of the MPC8241EC Rev. 10 specification. It supports single-data-rate SDRAM with programmable CAS latency, burst length, and refresh timing - but lacks DDR-specific features like differential clocks, DQS strobes, or double-data-rate transfer logic.
