Product details
Overview
MB89P475-102P-G-SH-JNE1 from Fujitsu (now Cypress) is an OTP-programmable 8-bit F2MC-8L microcontroller with 16 KB internal PROM, 1 KB RAM, 10-bit 8-channel ADC, UART/SIO, dual 8/16-bit timer/counters, PWM timer, PWC timer, buzzer output, and watchdog reset-designed for home appliance control systems requiring low-voltage operation (3.5–5.5 V) and multiple low-power modes.
For engineers reviewing the MB89P475-102P-G-SH-JNE1 datasheet, MB89P475-102P-G-SH-JNE1 pinout, MB89P475-102P-G-SH-JNE1 application, or MB89P475-102P-G-SH-JNE1 equivalent, this page delivers verified technical context, package mapping to 48-pin SH-DIP (DIP-48P-M01), real-time peripheral timing behavior, and validated alternative options for legacy design continuity.
Technical Context
The MB89P475 implements the proprietary F2MC-8L CPU core with 136 instructions, 8-bit data width, and variable instruction length (1–3 bytes); minimum execution time is 0.32 µs at 12.5 MHz. It supports dual-clock operation with subclock mode for watch functions and includes dedicated hardware for pulse width counting, PWM generation, and interval timing via 21-bit time-base timer.
Peripheral integration includes four edge-triggered external interrupts (INT10–INT13), five level-sensitive wake-up interrupts (INT20–INT24), synchronous/asynchronous UART/SIO with max 78.125 Kbps baud rate at 10 MHz, and software-selectable 7-frequency buzzer output using FCH/FCL clock sources.

| Hardware Timer Flexibility | Four 8/16-bit timers can be paired into two 16-bit units or used independently with event counting and square-wave output |
| ADC Auto-Triggering | 10-bit A/D converter supports repeated activation by internal timer-enables periodic sensor sampling without CPU intervention |
| Software-Configurable Buzzer | Seven fixed-frequency outputs derived from FCH/FCL clocks eliminate need for external tone generator circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C201A0-24LTXI | Capacitive touch-enabled PSoC 1 device; 16 KB flash, 1 KB RAM, no native 10-bit ADC (uses IDAC-based approx.) | Designed for touch UI replacement; lacks dedicated PWC/PWM timers and buzzer output | Choose only if migrating to capacitive touch interface and accepting ADC accuracy trade-off |
| MB89475-102P-G-SH-JNE1 | Mask-ROM version with identical pinout, same peripherals, but fixed 16 KB ROM and lower standby current | Same home appliance use cases; not reprogrammable post-manufacture | Select when production volume justifies mask ROM NRE and long-term supply stability is critical |
Compared with CY8C201A0-24LTXI, MB89P475 offers deterministic analog performance and dedicated timing hardware; compared with MB89475, it trades reprogrammability for slightly higher sleep-mode current-making it optimal for prototyping and low-volume appliance variants.

Manufacturer
Fujitsu Microelectronics (now part of Infineon via Cypress acquisition) specialized in high-reliability, low-power microcontrollers for consumer and industrial appliances before exiting the MCU business in 2012.
The MB89470 Series was designed specifically for cost-sensitive, high-volume home appliance applications demanding integrated analog peripherals, flexible timing, and robust low-power operation without external support ICs.
FAQ
Is MB89P475-102P-G-SH-JNE1 still in production?
No-MB89P475-102P-G-SH-JNE1 is obsolete per Fujitsu document DS07-12552-2E. It has no direct replacement, but Aetrix maintains legacy inventory and offers engineering support for continuity in existing designs. Cypress does not manufacture or support this part under CY prefix.
What programming tools are required for MB89P475 OTP PROM?
A dedicated Fujitsu MB89P475-compatible ROM programmer (e.g., System General SP6100 or custom socket-based PROM writer) is required. Programming must occur before soldering; in-circuit programming is not supported. Voltage and timing parameters follow Fujitsu's MB89P475 specification DS07-12552-2E Section 5.2.
Does MB89P475 support USB or CAN interfaces?
No-MB89P475 does not include USB or CAN physical layer or protocol stack hardware. Its only serial interface is UART/SIO (asynchronous/synchronous). Any USB or CAN connectivity requires external bridge ICs such as CP2102 or MCP2515, respectively.
How does the 21-bit time-base timer differ from standard 8/16-bit timers?
The 21-bit time-base timer provides four fixed interrupt periods (e.g., 0.66 ms to 335.5 ms at 12.5 MHz) derived from internal clock division-not software-configurable like the 8/16-bit timers. It serves as a precision system tick source for real-time scheduling, distinct from event-counting or PWM-capable timers.
