Notes on S-Mask Model  
(Single-Power-Supply Specification)  
There are two versions of the H8/3437F with on-chip flash memory: a dual-power-supply version  
and a single-power-supply (S-mask) version. Points to be noted when using the H8/3437F single-  
power-supply S-mask model are given below.  
1. Notes on Voltage Application  
12 V must not be applied to the S-mask model (single-power-supply specification), as this may  
permanently damage the device.  
The flash memory programming power supply for the S-mask model (single-power-supply  
specification) is VCC. The programming power supply for the dual-power-supply model is the FVPP  
pin (12 V), but the single-power-supply model (S-mask model) does not have an FVPP pin.  
Also, in boot mode, 12 V has to be applied to the MD1 pin in the dual-power-supply model, but 12  
V application is not necessary in the single-power-supply model (S-mask model).  
The maximum rating of the MD1 pin is VCC +0.3 V. Applying a voltage in excess of the  
maximum rating will permanently damage the device.  
Do not select the HN28F101 programmer setting for the S-mask model (single-power-supply  
specification). If this setting is made by mistake, 12 V will be applied to the STBY pin, possibly  
causing permanent damage to the device.  
When using a PROM programmer to program the on-chip flash memory in the S-mask model  
(single-power-supply specification), use a PROM programmer that supports Hitachi  
microcomputer devices with 64-kbyte on-chip flash memory. Also, only use the specified socket  
adapter. Using the wrong PROM programmer or socket adapter may damage the device.  
The following PROM programmers support the S-mask model (single-power-supply  
specification).  
DATA I/O: UNISITE, 2900, 3900, etc.  
Minato: 1892, 1891, 1890, etc.
